2018-04-11C++ify fileio_fh_t, replace VEC with std::vectorPedro Alves1-38/+42
Preparation for the next patch. - Replace VEC with std::vector. - Rewrite a couple macros as methods/functions. - While at it, rename fileio_fh_t::fd as fileio_fh_t::target_fd to avoid confusion between target and host file descriptors. gdb/ChangeLog: 2018-04-11 Pedro Alves <palves@redhat.com> * target.c (fileio_fh_t): Make it a named struct instead of a typedef. (fileio_fh_t::is_closed): New method. (DEF_VEC_O (fileio_fh_t)): Remove. (fileio_fhandles): Now a std::vector. (is_closed_fileio_fh): Delete. (acquire_fileio_fd): Adjust. Rename parameters. (release_fileio_fd): Adjust. (fileio_fd_to_fh): Reimplement as a function instead of a macro. (target_fileio_pwrite, target_fileio_pread, target_fileio_fstat) (target_fileio_close): Adjust.
2018-04-07Make target_read_alloc & al return vectorsSimon Marchi1-52/+34
This patch started by changing target_read_alloc_1 to return a byte_vector, to avoid manual memory management (in target_read_alloc_1 and in the callers). To communicate failures to the callers, it actually returns a gdb::optional<gdb::byte_vector>. Adjusting target_read_stralloc was a bit more tricky, since it wants to return a buffer of char, and not gdb_byte. Since you can't just cast a gdb::byte_vector into a gdb::def_vector<char>, I made target_read_alloc_1 templated, so both versions (that return vectors of gdb_byte and char) are generated. Since target_read_stralloc now returns a gdb::char_vector instead of a gdb::unique_xmalloc_ptr<char>, a few callers need to be adjusted. gdb/ChangeLog: * common/byte-vector.h (char_vector): New type. * target.h (target_read_alloc): Return gdb::optional<byte_vector>.

2018-03-30Change target_read_string to use unique_xmalloc_ptrTom Tromey1-2/+3
This changes the out parameter of target_read_string to be a unique_xmalloc_ptr. This avoids a cleanup and sets the stage for more cleanup removals.

2018-02-09btrace, gdbserver: remove the to_supports_btrace target methodMarkus Metzger1-8/+0
Remove the to_supports_btrace target method and instead rely on detecting errors when trying to enable recording. This will also provide a suitable error message explaining why recording is not possible. For remote debugging, gdbserver will now always advertise branch tracing related packets. When talking to an older GDB, this will cause GDB to try to enable branch tracing and gdbserver to report a suitable error message every time. An older gdbserver will not advertise branch tracing related packets if the one-time check failed, so a newer GDB with this patch will fail to enable branch tracing at remote_enable_btrace() rather than at btrace_enable(). The error message is the same in both cases so there should be no user-visible change. gdb/ * btrace.c (btrace_enable): Remove target_supports_btrace call. * nat/linux-btrace.c (perf_event_pt_event_type): Move.

2018-01-30Per-inferior target_terminal state, fix PR gdb/13211, morePedro Alves1-17/+106
In my multi-target branch I ran into problems with GDB's terminal handling that exist in master as well, with multi-inferior debugging. This patch adds a testcase for said problems (gdb.multi/multi-term-settings.exp), fixes the problems, fixes PR gdb/13211 as well (and adds a testcase for that too, gdb.base/interrupt-daemon.exp). The basis of the problem I ran into is the following. Consider a scenario where you have: - inferior 1 - started with "attach", process is running on some other terminal. - inferior 2 - started with "run", process is sharing gdb's terminal. In this scenario, when you stop/resume both inferiors, you want GDB to save/restore the terminal settings of inferior 2, the one that is sharing GDB's terminal. I.e., you want inferior 2 to "own" the terminal (in target_terminal::is_ours/target_terminal::is_inferior sense). Unfortunately, that's not what you get currently. Because GDB doesn't know whether an attached inferior is actually sharing GDB's terminal, it tries to save/restore its settings anyway, ignoring errors. In this case, this is pointless, because inferior 1 is running on a different terminal, but GDB doesn't know better. And then, because it is only possible to have the terminal settings of a single inferior be in effect at a time, or make one inferior/pgrp be the terminal's foreground pgrp (aka, only one inferior can "own" the terminal, ignoring fork children here), if GDB happens to try to restore the terminal settings of inferior 1 first, then GDB never restores the terminal settings of inferior 2. This patch fixes that and a few things more along the way: - Moves enum target_terminal::terminal_state out of the target_terminal class (it's currently private) and makes it a scoped enum so that it can be easily used elsewhere. - Replaces the inflow.c:terminal_is_ours boolean with a target_terminal_state variable. This allows distinguishing is_ours and is_ours_for_output states. This allows finally making child_terminal_ours_1 do something with its "output_only" parameter. - Makes each inferior have its own copy of the is_ours/is_ours_for_output/is_inferior state. - Adds a way for GDB to tell whether the inferior is sharing GDB's terminal. Works best on Linux and Solaris; the fallback works just as well as currently. - With that, we can remove the inf->attach_flag tests from child_terminal_inferior/child_terminal_ours. - Currently target_ops.to_ours is responsible for both saving the current inferior's terminal state, and restoring gdb's state. Because each inferior has its own terminal state (possibly handled by different targets in a multi-target world, even), we need to split the inferior-saving part from the gdb-restoring part. The patch adds a new target_ops.to_save_inferior target method for that. - Adds a new target_terminal::save_inferior() function, so that sequences like: scoped_restore_terminal_state save_state; target_terminal::ours_for_output (); ... restore back inferiors that were target_terminal_state::is_inferior before back to is_inferior, and leaves inferiors that were is_ours alone. - Along the way, this adds a default implementation of target_pass_ctrlc to inflow.c (for inf-child.c), that handles passing the Ctrl-C to a process running on GDB's terminal or to some other process otherwise. - Similarly, adds a new target default implementation of target_interrupt, for the "interrupt" command. The current implementation of this hook in inf-ptrace.c kills the whole process group, but that's incorrect/undesirable because we may not be attached to all processes in the process group. And also, it's incorrect because inferior_process_group() doesn't really return the inferior's real process group id if the inferior is not a process group leader... This is the cause of PR gdb/13211 [1], which this patch fixes. While at it, that target method's "ptid" parameter is eliminated, because it's not really used. - A new test is included that exercises and fixes PR gdb/13211, and also fixes a GDB issue reported on stackoverflow that I ran into while working on this [2]. The problem is similar to PR gdb/13211, except that it also triggers with Ctrl-C. When debugging a daemon (i.e., a process that disconnects from the controlling terminal and is not a process group leader, then Ctrl-C doesn't work, you just can't interrupt the inferior at all, resulting in a hung debug session. The problem is that since the inferior is no longer associated with gdb's session / controlling terminal, then trying to put the inferior in the foreground fails. And so Ctrl-C never reaches the inferior directly. pass_signal is only used when the inferior is attached, but that is not the case here. This is fixed by the new child_pass_ctrlc. Without the fix, the new interrupt-daemon.exp testcase fails with timeout waiting for a SIGINT that never arrives.

Ctrl+C terminates program when should break gdb. https://sourceware.org/bugzilla/show_bug.cgi?id=9425 The only way to fix that that I know of (without changing the kernel) is to make GDB put inferiors in a separate session (create a pseudo-tty master/slave pair, make the inferior run with the slave as its terminal, and have gdb pump output/input on the master end). gdb/ChangeLog: 2018-01-30 Pedro Alves <palves@redhat.com> PR gdb/13211 * config.in, configure: Regenerate. * configure.ac: Check for getpgid. * go32-nat.c (go32_pass_ctrlc): New.

2018-01-19Pass inferior down to target_detach and to_detachSimon Marchi1-3/+10
The to_detach target_ops method implementations are currently expected to work on current_inferior/inferior_ptid. In order to make things more explicit, and remove some "shadow" parameter passing through globals, this patch adds an "inferior" parameter to to_detach. Implementations will be expected to use this instead of relying on the global. However, to keep things simple, this patch only does the minimum that is necessary to add the parameter. The following patch gives an example of how one such implementation would be adapted. If the approach is deemed good, we can then look into adapting more implementations. Until then, they'll continue to work as they do currently. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Add inferior parameter.

2018-01-19Remove args from target detachSimon Marchi1-4/+4
I was looking into adding a parameter to target_detach, and was wondering what the args parameter was. It seems like in the distant past, it was possible to specify a signal number when detaching. That signal was injected in the process before it was detached. There is an example of code handling this in linux_nat_detach. With today's GDB, I can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work, because detach is a prefix command and doesn't recognize the sub-command 15. Doing "detach inferiors 15" doesn't work because it expects a list of inferior id to detach. Therefore, I don't think there's a way of invoking detach_command with a non-NULL args. I also didn't find any documentation related to this feature. I assume that this feature stopped working when detach was made a prefix command, which is in f73adfeb8bae36885e6ea248d12223ab0d5eb9cb (sorry, there's no commit title) from 2006. Given that this feature was broken for such a long time and we haven't heard anything (AFAIK, I did not find any related bug), I think it's safe to remove it, as well as the args parameter to target_detach. If someone wants to re-introduce it, I would suggest rethinking the user interface, and in particular would suggest using signal name instead of numbers. I tried to fix all the impacted code, but I might have forgotten some spots. It shouldn't be hard to fix if that's the case. I also couldn't build-test everything I changed, especially the nto and solaris stuff. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Remove args parameter.

2017-12-08Clear non-significant bits of address on memory accessYao Qi1-0/+2
ARMv8 supports tagged address, that is, the top one byte in address is ignored. It is always enabled on aarch64-linux. See https://www.kernel.org/doc/Documentation/arm64/tagged-pointers.txt The tag in the tagged address is modeled as non-significant bits in address, so this patch adds a new gdbarch method significant_addr_bit and clear the non-significant bits (the top byte in ARMv8) of the virtual address at the point before passing address to target cache layer. IOW, the address used in the target cache layer is already cleared.

2017-11-24regcache::cooked_read unit testYao Qi1-0/+47
This patch adds a unit test to regcache::cooked_read. This unit test is a little different from normal unit test, it is more about conformance test or interaction test. This test pass both raw register number and pseudo register number to regcache::cooked_read, in order to inspect 1) return value of cooked_read, 2) how are target_ops to_xfer_partial, to_{fetch,store}_registers called (because regcache is updated by means of these three target_ops methods). With this test here, we have a clear picture about how each port of GDB get cooked registers. This patch also shares some code on mock target. gdb: 2017-11-24 Yao Qi <yao.qi@linaro.org> * gdbarch-selftests.c (test_target_has_registers): Move it to target.c. (test_target_has_stack): Likewise.

2017-10-21Get rid of VEC (mem_region)Simon Marchi1-26/+18
This patch removes VEC (mem_region). Doing so requires touching a lot of little things here and there. The fields in mem_attrib are now initialized during construction. The values match those that were in default_mem_attrib (now removed). unknown_mem_attrib is also removed, and replaced with a static method (mem_attrib::unknown) that returns the equivalent. mem_region is initialized in a way similar to mem_region_init (now removed) did. I found the organization of mem_region_list and target_mem_region_list a bit confusing. Sometimes mem_region_list points to the same vector as target_mem_region_list (and therefore does not own it), and sometimes (when the user manually edits the mem regions) points to another vector, and in this case owns it. To avoid this ambiguity, I think it is simpler to have two vectors, one for target-defined regions and one for user-defined regions, and have mem_region_list point to one or the other. There are now no vector objects dynamically allocated, both are static. The make-target-delegates script does not generate valid code when a target method returns a type with a parameter list. For this reason, I created a typedef (mem_region_vector) that's only used in the target_ops structure. If you speak perl, you are welcome to improve the script! Regtested on the buildbot. gdb/ChangeLog: * memattr.h: Don't include vec.h. (struct mem_attrib): Initialize fields. <unknown>: New static method.

2017-10-11Constify add_prefix_cmdTom Tromey1-3/+1
This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

2017-10-04Fix "Remote 'g' packet reply is too long" problems with multiple inferiorsPedro Alves1-1/+3
When debugging two inferiors (or more) against gdbserver, and the inferiors have different architectures, such as e.g., on x86_64 GNU/Linux and one inferior is 64-bit while the other is 32-bit, then GDB can get confused with the different architectures in a couple spots. In both cases I ran into, GDB incorrectly ended up using the architecture of whatever happens to be the selected inferior instead of the architecture of some other given inferior: #1 - When parsing the expedited registers in stop replies. #2 - In the default implementation of the target_thread_architecture target method. These resulted in instances of the infamous "Remote 'g' packet reply is too long" error. For example, with the test added in this commit, we get: ~~~ Continuing. Remote 'g' packet reply is too long (expected 440 bytes, got 816 bytes): ad064000000000000[snip] (gdb) FAIL: gdb.multi/multi-arch.exp: inf1 event with inf2 selected: continue to hello_loop c Continuing.

2017-09-29Remove free_memory_read_result_vectorTom Tromey1-54/+21
This changes read_memory_robust to return a std::vector, allowing the removal of free_memory_read_result_vector and associated cleanups. This patch also changes the functions it touches to be a bit more robust with regards to deallocation; it's perhaps possible that read_memory_robust could have leaked in some situations. This patch is based on my earlier series to remove some MI cleanups. Regression tested by the buildbot. gdb/ChangeLog 2017-09-29 Tom Tromey <tom@tromey.com> * target.c (read_whatever_is_readable): Change type of "result". Update.

This adds two add_cmd overloads: one whose callback takes a const char *, and one that doesn't accept a function at all. The no-function overload was introduced to avoid ambiguity when NULL was passed as the function. Long term the goal is for all commands to take const arguments, and for the non-const variants to be removed entirely. gdb/ChangeLog 2017-09-27 Tom Tromey <tom@tromey.com> * cli/cli-decode.c (add_cmd, set_cmd_cfunc): New function overloads.

2017-09-21Add target method for converting thread handle to thread_info struct pointerKevin Buettner1-0/+9
This patch adds a target method named `to_thread_handle_to_thread_info'. It is intended to map a thread library specific thread handle (such as pthread_t for the pthread library) to the corresponding GDB internal thread_info struct (pointer). An implementation is provided for Linux pthreads; see linux-thread-db.c. gdb/ChangeLog: * target.h (struct target_ops): Add to_thread_handle_to_thread_info.

2017-09-20Remove make_cleanup_restore_target_terminalTom Tromey1-77/+23
This removes make_cleanup_restore_target_terminal and generally C++-ifies target terminal handling. It changes all target_terminal_* functions to be static members of a new target_terminal class and changes the cleanup to be a scoped_* class. make_cleanup_override_quit_handler is also removed in favor of simply using scoped_restore. Note that there are some files in this patch that I could not compile. Considering that some of the rewrites were automated, and that none of these files involed cleanups, I feel that this is relatively safe.

2017-03-23Remove some unnecessary inferior_ptid setting/restoring when ↵Simon Marchi1-4/+0
fetching/storing registers Now that the to_fetch_registers, to_store_registers and to_prepare_to_store target methods don't rely on the value of inferior_ptid anymore, we can remove a bunch of now unnecessary setting and restoring of inferior_ptid. The asserts added recently in target_fetch_registers and target_store_registers, which validate that inferior_ptid matches the regcache's ptid, must go away. It's the whole point of this effort, to not require inferior_ptid to have a particular value when calling these functions. One thing that I noticed is how sol-thread.c's ps_lgetregs and friends use the current value of inferior_ptid instead of what's passed as argument (ph->ptid), unlike proc-service.c's versions of the same functions. Is it expected? I left it like this in the current patch, but unless there's a good reason for it to be that way, I guess we should make it use the parameter. gdb/ChangeLog: * fbsd-tdep.c (fbsd_corefile_thread): Don't set/restore inferior_ptid. * proc-service.c (ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs): Likewise. * regcache.c (regcache_raw_update, regcache_raw_write): Likewise. * sol-thread.c (ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs): Likewise. * target.c (target_fetch_registers, target_store_registers): Remove asserts.
2017-03-13Add asserts in target_fetch/store_registersSimon Marchi1-0/+4
We are currently assuming that regcache->ptid is equal to inferior_ptid when we call target_fetch/store_registers. These asserts just validate that assumption. Also, since the following patches will change target code to use regcache->ptid instead of inferior_ptid, asserting that they are the same should ensure that our changes don't have any unintended consequences. gdb/ChangeLog: * target.c (target_fetch_registers, target_store_registers): Add assert.

2017-01-20Add command to erase all flash memory regionsLuis Machado1-0/+49
Changes in v4: - Replaced phex call with hex_string. Changes in v3: - Addressed comments by Pedro. - Output of memory region size now in hex format. - Misc formatting fixups. - Addressed Simon's comments on formatting. - Adjusted command text in the manual entry. - Fixed up ChangeLog. - Renamed flash_erase_all_command to flash_erase_command. Changes in v2: - Added NEWS entry. - Fixed long lines. - Address printing with paddress. Years ago we contributed flash programming patches upstream. The following patch is a leftover one that complements that functionality by adding a new command to erase all reported flash memory blocks. The command is most useful when we're dealing with flash-enabled targets (mostly bare-metal) and we need to reset the board for some reason. The wiping out of flash memory regions should help the target come up with a known clean state from which the user can load a new image and resume debugging. It is convenient enough to do this from the debugger, and there is also an MI command to expose this functionality to the IDE's. gdb/doc/ChangeLog: 2017-01-20 Mike Wrighton <mike_wrighton@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> * gdb.texinfo (-target-flash-erase): New MI command description.

2016-10-26gdb: Coalesce/aggregate (async) vCont packets/actionsPedro Alves1-0/+28
Currently, with "maint set target-non-stop on", that is, when gdb connects with the non-stop/asynchronous variant of the remote protocol, even with "set non-stop off", GDB always sends one vCont packet per thread resumed. This patch makes GDB aggregate and coalesce vCont packets, so we send vCont packets like "vCont;s:p1.1;c" in non-stop mode too. Basically, this is done by: - Adding a new target method target_commit_resume that is called after calling target_resume one or more times. When resuming a batch of threads, we'll only call target_commit_resume once after calling target_resume for all threads. - Making the remote target defer sending the actual vCont packet to target_commit_resume. Special care must be taken to avoid sending a vCont action with a "wildcard" thread-id (all threads of process / all threads) when that would resume threads/processes that should not be resumed. See remote_commit_resume comments for details. Unlike all-stop's remote_resume implementation, this handles the case of too many actions resulting in a too-big vCont packet, by flushing the vCont packet and starting a new one. E.g., imagining that the "c" action in: vCont;s:1;c overflows the packet buffer, we split the actions like: vCont;s:1 vCont;c Tested on x86_64 Fedora 20, with and without "maint set target-non-stop on". Also tested with a hack that makes remote_commit_resume flush the vCont packet after every action appended (which caught a few bugs). gdb/ChangeLog: 2016-10-26 Pedro Alves <palves@redhat.com> * inferior.h (ALL_NON_EXITED_INFERIORS): New macro. * infrun.c (do_target_resume): Call target_commit_resume.

2016-10-06Consolidate API of target_supports_multi_processSergio Durigan Junior1-0/+8
This simple commit consolidates the API of target_supports_multi_process. Since both GDB and gdbserver use the same function prototype, all that was needed was to move create this prototype on gdb/target/target.h and turn the macros declared on gdb/{,gdbserver/}target.h into actual functions. Regtested (clean pass) on the BuildBot. gdb/ChangeLog: 2016-10-06 Sergio Durigan Junior <sergiodj@redhat.com> * target.c (target_supports_multi_process): New function, moved from... * target.h (target_supports_multi_process): ... here.

2016-09-19Consolidate target_mourn_inferior between GDB and gdbserverSergio Durigan Junior1-1/+2
This patch consolidates the API of target_mourn_inferior between GDB and gdbserver, in my continuing efforts to make sharing the fork_inferior function possible between both. GDB's version of the function did not care about the inferior's ptid being mourned, but gdbserver's needed to know this information. Since it actually makes sense to pass the ptid as an argument, instead of depending on a global value directly (which GDB's version did), I decided to make the generic API to accept it. I then went on and extended all calls being made on GDB to include a ptid argument (which ended up being inferior_ptid most of the times, anyway), and now we have a more sane interface. On GDB's side, after talking to Pedro a bit about it, we decided that just an assertion to make sure that the ptid being passed is equal to inferior_ptid would be enough for now, on the GDB side. We can remove the assertion and perform more operations later if we ever pass anything different than inferior_ptid. Regression tested on our BuildBot, everything OK. I'd appreciate a special look at gdb/windows-nat.c's modification because I wasn't really sure what to do there. It seemed to me that maybe I should build a ptid out of the process information there, but then I am almost sure the assertion on GDB's side would trigger. gdb/ChangeLog: 2016-09-19 Sergio Durigan Junior <sergiodj@redhat.com> * darwin-nat.c (darwin_kill_inferior): Adjusting call to target_mourn_inferior to include ptid_t argument. * fork-child.c (startup_inferior): Likewise. * gnu-nat.c (gnu_kill_inferior): Likewise. * inf-ptrace.c (inf_ptrace_kill): Likewise. * infrun.c (handle_inferior_event_1): Likewise. * linux-nat.c (linux_nat_attach): Likewise.

2016-09-01Share target_wait prototype between GDB and gdbserverSergio Durigan Junior1-0/+2
This commit moves the target_wait prototype from the GDB-specific target.h header to the common target/target.h header. Then, it creates a compatible implementation of target_wait on gdbserver using the_target->wait, and adjusts the (only) caller (mywait function). Pretty straightforward, no regressions introduced. gdb/gdbserver/ChangeLog: 2016-09-01 Sergio Durigan Junior <sergiodj@redhat.com> * target.c (mywait): Call target_wait instead of the_target->wait.

2016-09-01Use target_continue{,_no_signal} instead of target_resumeSergio Durigan Junior1-0/+8
This commit implements a new function, target_continue, on top of the target_resume function. Then, it replaces all calls to target_resume by calls to target_continue or to the already existing target_continue_no_signal. This is one of the (many) necessary steps needed to consolidate the target interface between GDB and gdbserver. In particular, I am interested in the impact this change will have on the unification of the fork_inferior function (which I have been working on). Tested on the BuildBot, no regressions introduced. gdb/gdbserver/ChangeLog: 2016-09-31 Sergio Durigan Junior <sergiodj@redhat.com> * server.c (start_inferior): New variable 'ptid'.
