2020-05-27Don't close process handle provided by WaitForDebugEventHannes Domani1-0/+6
Only the process handle returned by OpenProcess or CreateProcess needs to be closed, the one provided by WaitForDebugEvent is closed automatically. gdbserver/ChangeLog: 2020-05-27 Hannes Domani <ssbssa@yahoo.de> * win32-low.cc (do_initial_child_stuff): Set open_process_used. (win32_clear_inferiors): Use open_process_used. (get_child_debug_event): Likewise.
2020-05-25Use construct_inferior_arguments which handles special charsMichael Weghorn1-0/+13
Use the construct_inferior_arguments function instead of stringify_argv to construct a string from the program arguments in those places where that one is then passed to fork_inferior (linux-low, lyn-low), since construct_inferior_arguments properly takes care of special characters, while stringify_argv does not. Using construct_inferior_arguments seems "natural", since its documentation also mentions that it "does the same shell processing as fork_inferior". Since construct_inferior_args has been extended to do proper quoting for Windows shells in commit 5d60742e2dd3c9b475dce54b56043a358751bbb8 ("Fix quoting of special characters for the MinGW build.", 2012-06-12), use it for the Windows case as well. (I could not test that case myself, though.) Adapt handling of empty args in function 'handle_v_run' in gdbserver/server.cc to just insert an empty string for an empty arg, since that one is now properly handled in 'construct_inferior_arguments' already (and inserting a "''" string in 'handle_v_run' would otherwise cause that one to be treated as a string literally containing two quote characters, which 'construct_inferior_args' would preserve by adding extra escaping). This makes gdbserver properly handle program args containing special characters (like spaces), e.g. (example from PR25893) $ gdbserver localhost:50505 myprogram "hello world" now properly handles "hello world" as a single arg, not two separate ones ("hello", "world"). gdbserver/ChangeLog: PR gdbserver/25893 * linux-low.cc (linux_process_target::create_inferior), lynx-low.cc (lynx_process_target::create_inferior), win32-low.cc (win32_process_target::create_inferior): Use construct_inferior_arguments instead of stringify_argv to get string representation which properly escapes special characters. * server.cc (handle_v_run): Just pass empty program arg as such, since any further processing is now handled via construct_inferior_arguments.

2020-05-25nto_process_target::create_inferior: Pass args as char **Michael Weghorn1-0/+5
According to [1], the fifth parameter to the 'spawnp' function is 'char * const argv[]', so just pass the args contained in the vector as an array right away, rather than converting that to a C string first and passing that one. With commit 2090129c36c7e582943b7d300968d19b46160d84 ("Share fork_inferior et al with gdbserver", 2016-12-22) the type had changed from 'char **' to 'char *', but I can't see an apparent reason for that, and 'nto_procfs_target::create_inferior' (in gdb/nto-procfs.c) also passes a 'char **' to 'spawnp' instead. I do not know much about that target and cannot actually test this, however. The main motivation to look at this was identifying and replacing the remaining uses of the 'stringify_argv' function which does not properly do escaping. [1] http://www.qnx.com/developers/docs/7.0.0/#com.qnx.doc.neutrino.lib_ref/topic/s/spawnp.html gdbserver/ChangeLog: * nto-low.cc (nto_process_target::create_inferior): Pass argv to spawnp function as char **.

2020-05-25gdbserver: Don't add extra NULL to program argsMichael Weghorn1-0/+5
The vector holding the program args is passed as a parameter to target_create_inferior, which then passes it to stringify_argv for all platforms, where any NULL entry in the vector is ignored, so there seems to be no reason to actually add one after all. (Since the intention is to replace uses of stringify_argv with construct_inferior_arguments in a follow-up commit and that function doesn't currently handle such NULL arguments, it would otherwise have to be extended.) gdbserver/ChangeLog: * server.cc (captured_main), (handle_v_run): No longer insert extra NULL element to args vector.

2020-05-23Use safe-ctype.h (ISSPACE etc.) in symbol parsing & comparisonPedro Alves1-0/+4
This patch avoids depending on the current locale when parsing & comparing symbol names, by using libiberty's safe-ctype.h uppercase TOLOWER, ISXDIGIT, etc. macros instead of the standard ctype.h tolower, isxdigit, etc. macros/functions. This commit: commit b1b60145aedb8adcb0b9dcf43a5ae735c2f03b51 Author: Pedro Alves <palves@redhat.com> AuthorDate: Tue May 22 17:35:38 2018 +0100 Support UTF-8 identifiers in C/C++ expressions (PR gdb/22973) did something similar, except in the expression parser. This can improve GDB's symbol loading performance significantly. Currently strcmp_iw_ordered can show up high on profiles (called from sort_pst_symbols -> std::sort) because of the isspace and tolower functions. Hannes mentions seeing it as high as in ~24% of the profiling samples on Windows (https://sourceware.org/pipermail/gdb-patches/2020-May/168858.html). I tested GDB's performance (built with "-g -O2") loading a "-g -O0" build of gdb. I ran GDB 10 times like: /bin/time -f %e \ ./gdb/gdb --data-directory ./gdb/data-directory -nx \ -batch /tmp/gdb-g-O0 Then I computed the mean time. The baseline mean time was gdb 2.515 This patch brings the number down to gdb 2.096 Which is an around 16% improvement. gdb/ChangeLog: 2020-05-23 Pedro Alves <palves@redhat.com> * utils.c: Include "gdbsupport/gdb-safe-ctype.h". (parse_escape): Use ISDIGIT instead of isdigit. (puts_debug): Use gdb_isprint instead of isprint. (fprintf_symbol_filtered): Use ISALNUM instead of isalnum. (cp_skip_operator_token, skip_ws, strncmp_iw_with_mode): Use ISSPACE instead of isspace. (strncmp_iw_with_mode): Use TOLOWER instead of tolower and ISSPACE instead of isspace.

2020-04-27gdb, gdbserver: remove configure check for fs_base/gs_base in user_regs_structSimon Marchi1-0/+9
I recently stumbled on this code mentioning Linux kernel 2.6.25, and thought it could be time for some spring cleaning (newer GDBs probably don't need to supports 12-year old kernels). I then found that the "legacy" case is probably broken anyway, which gives an even better motivation for its removal. In short, this patch removes the configure checks that check if user_regs_struct contains the fs_base/gs_base fields and adjusts all uses of the HAVE_STRUCT_USER_REGS_STRUCT_{FS,GS}_BASE macros. The longer explanation/rationale follows. Apparently, Linux kernels since 2.6.25 (that's from 2008) have been reliably providing fs_base and gs_base as part of user_regs_struct. Commit df5d438e33d7 in the Linux kernel [1] seems related. This means that we can get these values by reading registers with PTRACE_GETREGS. Previously, these values were obtained using a separate PTRACE_ARCH_PRCTL ptrace call. First, I'm not even sure the configure check was really right in the first place. The user_regs_struct used by GDB comes from /usr/include/x86_64-linux-gnu/sys/user.h (or equivalent on other distros) and is provided by glibc. glibc has had the fs_base/gs_base fields in there for a very long time, at least since this commit from 2001 [2]. The Linux kernel also has its version of user_regs_struct, which I think was exported to user-space at some point. It included the fs_base/gs_base fields since at least this 2002 commit [3]. In any case, my conclusion is that the fields were there long before the aforementioned Linux kernel commit. The kernel commit didn't add these fields, it only made sure that they have reliable values when obtained with PTRACE_GETREGS. So, checking for the presence of the fs_base/gs_base fields in struct user_regs_struct doesn't sound like a good way of knowing if we can reliably get the fs_base/gs_base values from PTRACE_GETREGS. My guess is that if we were using that strategy on a < 2.6.25 kernel, things would not work correctly: - configure would find that the user_regs_struct has the fs_base/gs_base fields (which are probided by glibc anyway) - we would be reading the fs_base/gs_base values using PTRACE_GETREGS, for which the kernel would provide unreliable values Second, I have tried to see how things worked by forcing GDB to not use fs_base/gs_base from PTRACE_GETREGS (forcing it to use the "legacy" code, by configuring with ac_cv_member_struct_user_regs_struct_gs_base=no ac_cv_member_struct_user_regs_struct_fs_base=no Doing so breaks writing registers back to the inferior. For example, calling an inferior functions gives an internal error: (gdb) p malloc(10) /home/smarchi/src/binutils-gdb/gdb/i387-tdep.c:1408: internal-error: invalid i387 regnum 152 The relevant last frames where this error happens are: #8 0x0000563123d262fc in internal_error (file=0x563123e93fd8 "/home/smarchi/src/binutils-gdb/gdb/i387-tdep.c", line=1408, fmt=0x563123e94482 "invalid i387 regnum %d") at /home/smarchi/src/binutils-gdb/gdbsupport/errors.cc:55 #9 0x0000563123047d0d in i387_collect_xsave (regcache=0x5631269453f0, regnum=152, xsave=0x7ffd38402a20, gcore=0) at /home/smarchi/src/binutils-gdb/gdb/i387-tdep.c:1408 #10 0x0000563122c69e8a in amd64_collect_xsave (regcache=0x5631269453f0, regnum=152, xsave=0x7ffd38402a20, gcore=0) at /home/smarchi/src/binutils-gdb/gdb/amd64-tdep.c:3448 #11 0x0000563122c5e94c in amd64_linux_nat_target::store_registers (this=0x56312515fd10 <the_amd64_linux_nat_target>, regcache=0x5631269453f0, regnum=152) at /home/smarchi/src/binutils-gdb/gdb/amd64-linux-nat.c:335 #12 0x00005631234c8c80 in target_store_registers (regcache=0x5631269453f0, regno=152) at /home/smarchi/src/binutils-gdb/gdb/target.c:3485 #13 0x00005631232e8df7 in regcache::raw_write (this=0x5631269453f0, regnum=152, buf=0x56312759e468 "@\225\372\367\377\177") at /home/smarchi/src/binutils-gdb/gdb/regcache.c:765 #14 0x00005631232e8f0c in regcache::cooked_write (this=0x5631269453f0, regnum=152, buf=0x56312759e468 "@\225\372\367\377\177") at /home/smarchi/src/binutils-gdb/gdb/regcache.c:778 #15 0x00005631232e75ec in regcache::restore (this=0x5631269453f0, src=0x5631275eb130) at /home/smarchi/src/binutils-gdb/gdb/regcache.c:283 #16 0x0000563123083fc4 in infcall_suspend_state::restore (this=0x5631273ed930, gdbarch=0x56312718cf20, tp=0x5631270bca90, regcache=0x5631269453f0) at /home/smarchi/src/binutils-gdb/gdb/infrun.c:9103 #17 0x0000563123081eed in restore_infcall_suspend_state (inf_state=0x5631273ed930) at /home/smarchi/src/binutils-gdb/gdb/infrun.c:9151 The problem seems to be that amd64_linux_nat_target::store_registers calls amd64_native_gregset_supplies_p to know whether gregset provides fs_base. When !HAVE_STRUCT_USER_REGS_STRUCT_FS_BASE, amd64_native_gregset_supplies_p returns false. store_registers therefore assumes that it must be an "xstate" register. This is of course wrong, and that leads to the failed assertion when i387_collect_xsave doesn't recognize the register. amd64_linux_nat_target::store_registers could probably be fixed to handle this case, but I don't think it's worth it, given that it would only be to support very old kernels.

This is needed to properly handle queued stops. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (wait_for_debug_event): Move to nat/windows-nat.c. * nat/windows-nat.h (wait_for_debug_event): Declare. * nat/windows-nat.c (wait_for_debug_event): Move from windows-nat.c. No longer static. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.c (win32_kill, get_child_debug_event): Use wait_for_debug_event.
2020-04-08Share some inferior-related Windows codeTom Tromey1-0/+4
This adds a couple of functions to nat/windows-nat.c and changes gdb and gdbserver to use them. One function checks the list of pending stops for a match (not yet used by gdbserver, but will be in a subsequent patch); and the other is a wrapper for ContinueDebugEvent that always uses the last "real" stop event. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (windows_continue): Use matching_pending_stop and continue_last_debug_event. * nat/windows-nat.h (matching_pending_stop) (continue_last_debug_event): Declare. * nat/windows-nat.c (DEBUG_EVENTS): New define. (matching_pending_stop, continue_last_debug_event): New functions. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.c (child_continue): Call continue_last_debug_event.
2020-04-08Share handle_exceptionTom Tromey1-0/+8
Both gdb and gdbserver have a "handle_exception" function, the bulk of which is shared between the two implementations. This patch arranges for the entire thing to be moved into nat/windows-nat.c, with the differences handled by callbacks. This patch introduces one more callback to make this possible. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (MS_VC_EXCEPTION): Move to nat/windows-nat.c.

2020-04-08Share handle_load_dll and handle_unload_dll declarationsTom Tromey1-0/+7
This changes nat/windows-nat.h to declare handle_load_dll and handle_unload_dll. The embedding application is required to implement these -- while the actual code was difficult to share due to some other differences between the two programs, sharing the declaration lets a subsequent patch share more code that uses these as callbacks. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (windows_nat::handle_load_dll) (windows_nat::handle_unload_dll): Rename.

2020-04-08Normalize handle_output_debug_string APITom Tromey1-0/+6
This changes gdbserver's implementation of handle_output_debug_string to have the same calling convention as that of gdb. This allows for sharing some more code in a subsequent patch. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (windows_nat::handle_output_debug_string): Rename.

2020-04-08Share thread_rec between gdb and gdbserverTom Tromey1-0/+8
This changes gdb and gdbserver to use the same calling convention for the "thread_rec" helper function. Fully merging these is difficult due to differences in how threads are managed by the enclosing applications; but sharing a declaration makes it possible for future shared code to call this method. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (enum thread_disposition_type): Move to nat/windows-nat.h.

This wraps the shared windows-nat code in a windows_nat namespace. This helps avoid name clashes. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c: Add "using namespace". * nat/windows-nat.h: Wrap contents in windows_nat namespace. * nat/windows-nat.c: Wrap contents in windows_nat namespace. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.h (struct win32_target_ops): Use qualified names where needed. * win32-i386-low.c: Add "using namespace". * win32-low.c: Add "using namespace". * win32-arm-low.c: Add "using namespace".

2020-04-08Share windows_thread_info between gdb and gdbserverTom Tromey1-0/+4
This introduces a new file, nat/windows-nat.h, which holds the definition of windows_thread_info. This is now shared between gdb and gdbserver. Note that the two implementations different slightly. gdb had a couple of fields ("name" and "reload_context") that gdbserver did not; while gdbserver had one field ("base_context") that gdb did not, plus better comments. The new file preserves all the fields, and the comments. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (struct windows_thread_info): Remove. * nat/windows-nat.h: New file. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.h (struct windows_thread_info): Remove.
