2014-05-21Fix TLS access for -static -pthreadJan Kratochvil9-32/+131
I have posted: TLS variables access for -static -lpthread executables https://sourceware.org/ml/libc-help/2014-03/msg00024.html and the GDB patch below has been confirmed as OK for current glibcs. Further work should be done for newer glibcs: Improve TLS variables glibc compatibility https://sourceware.org/bugzilla/show_bug.cgi?id=16954 Still the patch below implements the feature in a fully functional way backward compatible with current glibcs, it depends on the following glibc source line: csu/libc-tls.c main_map->l_tls_modid = 1; gdb/ 2014-05-21 Jan Kratochvil <jan.kratochvil@redhat.com> Fix TLS access for -static -pthread. * linux-thread-db.c (struct thread_db_info): Add td_thr_tlsbase_p.

2014-05-21Make the dcache (code/stack cache) handle line reading errors betterPedro Alves5-2/+190
The dcache (code/stack cache) is supposed to be transparent, but it's actually not in one case. dcache tries to read chunks (cache lines) at a time off of the target. This may end up trying to read unaccessible or unavailable memory. Currently the caller gets an xfer error in this case. But if the specific bits of memory the caller actually wanted are available and accessible, then the caller should get the memory it wanted, not an error. gdb/ 2014-05-21 Pedro Alves <palves@redhat.com> * dcache.c (dcache_read_memory_partial): If reading the cache line fails, fallback to reading just the memory the caller wanted. gdb/testsuite/ 2014-05-21 Pedro Alves <palves@redhat.com> * gdb.base/dcache-line-read-error.c: New. * gdb.base/dcache-line-read-error.exp: New.

2014-05-20Make compare-sections work against all targets; add compare-sections [-r] tests.Pedro Alves11-40/+316
This does two things: 1. Adds a test. Recently compare-sections got a new "-r" switch, but given no test existed for compare-sections, the patch was allowed in with no testsuite addition. This now adds a test for both compare-sections and compare-sections -r. 2. Makes the compare-sections command work against all targets. Currently, compare-sections only works with remote targets, and only those that support the qCRC packet. The patch makes it so that if the target doesn't support accelerating memory verification, then GDB falls back to comparing memory itself. This is of course slower, but it's better than nothing, IMO. While testing against extended-remote GDBserver I noticed that we send the qCRC request to the target if we're connected, but not yet running a program. That can't work of course -- the patch fixes that. This all also goes in the direction of bridging the local/remote parity gap. I didn't decouple 1. from 2., because that would mean that the test would need to handle the case of the target not supporting the command. Tested on x86_64 Fedora 17, native, remote GDBserver, and extended-remote GDBserver. I also hack-disabled qCRC support to make sure the fallback paths in remote.c work. gdb/doc/ 2014-05-20 Pedro Alves <palves@redhat.com> * gdb.texinfo (Memory) <compare-sections>: Generalize comments to not be remote specific.

2014-05-20[GDBserver] Make Zx/zx packet handling idempotent.Pedro Alves25-411/+1300
This patch fixes hardware breakpoint regressions exposed by my fix for "PR breakpoints/7143 - Watchpoint does not trigger when first set", at https://sourceware.org/ml/gdb-patches/2014-03/msg00167.html The testsuite caught them on Linux/x86_64, at least. gdb.sum: gdb.sum: FAIL: gdb.base/hbreak2.exp: next over recursive call FAIL: gdb.base/hbreak2.exp: backtrace from factorial(5.1) FAIL: gdb.base/hbreak2.exp: continue until exit at recursive next test gdb.log: (gdb) next Program received signal SIGTRAP, Trace/breakpoint trap. factorial (value=4) at ../../../src/gdb/testsuite/gdb.base/break.c:113 113 if (value > 1) { /* set breakpoint 7 here */ (gdb) FAIL: gdb.base/hbreak2.exp: next over recursive call Actually, that patch just exposed a latent issue to "breakpoints always-inserted off" mode, not really caused it. After that patch, GDB no longer removes breakpoints at each internal event, thus making some scenarios behave like breakpoint always-inserted on. The bug is easy to trigger with always-inserted on. The issue is that since the target-side breakpoint conditions support, if the stub/server supports evaluating breakpoint conditions on the target side, then GDB is sending duplicate Zx packets to the target without removing them before, and GDBserver is not really expecting that for Z packets other than Z0/z0. E.g., with "set breakpoint always-inserted on" and "set debug remote 1": (gdb) b main Sending packet: $m410943,1#ff...Packet received: 48 Breakpoint 4 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.

On the GDBserver side (with monitor set debug-hw-points 1), in the Z1 case, we see: $ ./gdbserver :9999 ./gdbserver Process ./gdbserver created; pid = 8629 Listening on port 9999 Remote debugging from host 127.0.0.1 insert_watchpoint (addr=410943, len=1, type=instruction-execute): CONTROL (DR7): 00000101 STATUS (DR6): 00000000 DR0: addr=0x410943, ref.count=1 DR1: addr=0x0, ref.count=0 DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0 insert_watchpoint (addr=410943, len=1, type=instruction-execute): CONTROL (DR7): 00000101 STATUS (DR6): 00000000 DR0: addr=0x410943, ref.count=2 DR1: addr=0x0, ref.count=0 DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0 insert_watchpoint (addr=410943, len=1, type=instruction-execute): CONTROL (DR7): 00000101 STATUS (DR6): 00000000 DR0: addr=0x410943, ref.count=3 DR1: addr=0x0, ref.count=0 DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0 insert_watchpoint (addr=410943, len=1, type=instruction-execute): CONTROL (DR7): 00000101 STATUS (DR6): 00000000 DR0: addr=0x410943, ref.count=4 DR1: addr=0x0, ref.count=0 DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0 insert_watchpoint (addr=410943, len=1, type=instruction-execute): CONTROL (DR7): 00000101 STATUS (DR6): 00000000 DR0: addr=0x410943, ref.count=5 DR1: addr=0x0, ref.count=0 DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0 remove_watchpoint (addr=410943, len=1, type=instruction-execute): CONTROL (DR7): 00000101 STATUS (DR6): 00000000 DR0: addr=0x410943, ref.count=4 DR1: addr=0x0, ref.count=0 DR2: addr=0x0, ref.count=0 DR3: addr=0x0, ref.count=0 That's one insert_watchpoint call for each Z1 packet, and then one remove_watchpoint call for the z1 packet. Notice how ref.count increased for each insert_watchpoint call, and then in the end, after GDB told GDBserver to forget about the hardware breakpoint, GDBserver ends with the the first debug register still with ref.count=4! IOW, the hardware breakpoint is left armed on the target, while on the GDB end it's gone. If the program happens to execute 0x410943 afterwards, then the CPU traps, GDBserver reports the trap to GDB, and GDB not having a breakpoint set at that address anymore, reports to the user a spurious SIGTRAP. This is exactly what is happening in the hbreak2.exp test, though in that case, it's a shared library event that triggers a breakpoint_re_set, when breakpoints are still inserted (because nowadays GDB doesn't remove breakpoints while handling internal events), and that recreates breakpoint locations, which likewise forces breakpoint reinsertion and Zx packet resends... That is a lot of bogus Zx duplication that should possibly be addressed on the GDB side. GDB resends Zx packets because the way to change the target-side condition, is to resend the breakpoint to the server with the new condition. (That's an option in the packet: e.g., "Z1,410943,1;X3,220027" for "hbreak main if 0". The packets in the examples above are shorter because the breakpoints don't have conditions attached). GDB doesn't remove the breakpoint first before reinserting it because that'd be bad for non-stop, as it'd open a window where the inferior could miss the breakpoint. The conditions actually haven't changed between the resends, but GDB isn't smart enough to realize that. (TBC, if the target doesn't support target-side conditions, then GDB doesn't trigger these resends (init_bp_location calls mark_breakpoint_location_modified, and that does nothing if condition evaluation is on the host side. The resends are caused by the 'loc->condition_changed = condition_modified.' line.) But, even if GDB was made smarter, GDBserver should really still handle the resends anyway. So target-side conditions also aren't really to blame. The documentation of the Z/z packets says: "To avoid potential problems with duplicate packets, the operations should be implemented in an idempotent way." As such, we may want to fix GDB, but we should definitely fix GDBserver. The fix is a prerequisite for target-side conditions on hardware breakpoints anyway (and while at it, on watchpoints too). GDBserver indeed already treats duplicate Z0 packets in an idempotent way. mem-break.c has the concept of high-level and low-level breakpoints, somewhat similar to GDB's split of breakpoints vs breakpoint locations, and keeps track of multiple breakpoints referencing the same address/location, for the case of an internal GDBserver breakpoint or a tracepoint being set at the same address as a GDB breakpoint. But, it only allows GDB to ever contribute one reference to a software breakpoint location. IOW, if gdbserver sees a Z0 packet for the same address where it already had a GDB breakpoint set, then GDBserver won't create another high-level GDB breakpoint. However, mem-break.c only tracks GDB Z0 breakpoints. The same logic should apply to all kinds of Zx packets. Currently, gdbserver passes down each duplicate Zx (other than Z0) request directly to the target->insert_point routine. The x86 watchpoint support itself refcounts watchpoint / hw breakpoint requests, to handle overlapping watchpoints, and save debug registers. But that code doesn't (and really shouldn't) handle the duplicate requests, assuming that for each insert there will be a corresponding remove. So the fix is to generalize mem-break.c to track all kinds of Zx breakpoints, and filter out duplicates. As mentioned, this ends up adding support for target-side conditions on hardware breakpoints and watchpoints too (though GDB itself doesn't support the latter yet). Probably the least obvious change in the patch is that it kind of turns the breakpoint insert/remove APIs inside out. Before, the target methods were only called for GDB breakpoints. The internal breakpoint set/delete methods inserted memory breakpoints directly bypassing the insert/remove target methods. That's not good when the target should use a debug API to set software breakpoints, instead of relying on GDBserver patching memory with breakpoint instructions, as is the case of NTO. Now removal/insertion of all kinds of breakpoints/watchpoints, either internal, or from GDB, always go through the target methods. The insert_point/remove_point methods no longer get passed a Z packet type, but an internal/raw breakpoint type. They're also passed a pointer to the raw breakpoint itself (note that's still opaque outside mem-break.c), so that insert_memory_breakpoint / remove_memory_breakpoint have access to the breakpoint's shadow buffer. I first tried passing down a new structure based on GDB's "struct bp_target_info" (actually with that name exactly), but then decided against it as unnecessary complication. As software/memory breakpoints work by poking at memory, when setting a GDB Z0 breakpoint (but not internal breakpoints, as those can assume the conditions are already right), we need to tell the target to prepare to access memory (which on Linux means stop threads). If that operation fails, we need to return error to GDB. Seeing an error, if this is the first breakpoint of that type that GDB tries to insert, GDB would then assume the breakpoint type is supported, but it may actually not be. So we need to check whether the type is supported at all before preparing to access memory. And to solve that, the patch adds a new target->supports_z_point_type method that is called before actually trying to insert the breakpoint. Other than that, hopefully the change is more or less obvious. New test added that exercises the hbreak2.exp regression in a more direct way, without relying on a breakpoint re-set happening before main is reached.

2014-05-20[GDBserver][AArch64] Make watchpoint support use target_hw_bp_type.Pedro Alves2-39/+82
This makes linux-aarch64-low.c use target_hw_bp_type, like gdb's aarch64-linux-nat.c. The original motivation is decoupling insert_point/remove_point from Z packet numbers, but I think making the files a little bit more similar is a good thing on its own right. Ideally we'd merge these files even... The aarch64_point_encode_ctrl_reg change is taken straight from GDB's copy.

2014-05-20Do not build gdbserver with -Werror by default if development=falseJoel Brobecker3-4/+10
On GDB release branches, we change $development in gdb/development.sh to false, in order to build the GDB release without -Werror by default, thus avoiding harmless compiler warnings from breaking the build of someone who's only interested in building GDB rather than working on it. This patch implements the same strategy for gdbserver, using the exact same method. gdb/gdbserver/ChangeLog: * configure.ac: Only use -Werror by default when DEVELOPMENT is true. * configure: Regenerate. Tested on x86_64-linux, by rebuilding GDBserver first with development set to true, and then doing it again with development set to false. Werror was used in the first case, but not in the second.

2014-05-20Set timeout for gdb.reverse/*.exp test casesYao Qi3-0/+21
Hi, This patch is to add a new board setting gdb_reverse_timeout, which is used to set timeout for all gdb.reverse test cases, which are usually very slow and cause some TIMEOUT failures, for example, on some arm boards. We have some alternatives to this approach, but I am not satisfied with them: - Increase the timeout value. This is the global change, and it may cause some delay where actual failures happen. - Set timeout by gdb_reverse_timeout in every gdb.reverse/*.exp. Then, we have to touch every file under gdb.reverse. In this patch, we choose a central place to set timeout for all tests in gdb.reverse, which is convenient. gdb/testsuite: 2014-05-20 Yao Qi <yao@codesourcery.com> * lib/gdb.exp (gdb_init): Set timeout if test file is under gdb.reverse directory and gdb_reverse_timeout exists in board setting. * README: Document gdb_reverse_timeout.
2014-05-20gdb_init argument ARGS is a string rather than a listYao Qi2-10/+12
The argument ARGS of gdb_init is passed from dejagnu is a string, the test file name. In dejagnu/runtest.exp: proc runtest { test_file_name } { .... .... if [info exists tool] { if { [info procs "${tool}_init"] != "" } { ${tool}_init $test_file_name; } } .... } but inn default_gdb_init (callee of gdb_init), we have set gdb_test_file_name [file rootname [file tail [lindex $args 0]]] In tcl, all actual arguments are combined to a list and assigned to args. This code here isn't wrong, but unnecessary, because its caller (proc runtest) only passes one string to it, and IMO, we don't need such tricky tcl "args". I doubt that "[lindex $args 0]" is to be backward compatible with old dejagnu, but dejagnu-1.4 release started to pass $test_file_name to ${too}_init, as I showed above. dejagnu-1.4 was released in 2001, and it should be old enough. I also tried to check whether gdb testusite works with dejagnu-1.3 or not, but failed to build dejagnu-1.3 on my machine. Supposing GDB testsuite requires at least dejagnu-1.4, this change should be safe. This patch is update default_gdb_init to treat ARGS as a string instead of a list. Then, 'args' sounds like a list, and this patch also renames it by 'test_file_name', to align with dejagnu. gdb/testsuite: 2014-05-20 Yao Qi <yao@codesourcery.com> * lib/gdb.exp (default_gdb_init): Rename argument 'args' by 'test_file_name'. Treat args as a string instead of a list. (gdb_init): Rename argument 'args' by 'test_file_name'.
2014-05-20Fix issue #15778: GDB Aarch64 signal frame unwinder issueHui Zhu2-29/+41
The root cause of this issue is unwinder of "#3 <signal handler called>" doesn't supply right values of registers. When GDB want to get the previous frame of "#3 <signal handler called>", it will call cache init function of unwinder "aarch64_linux_sigframe_init". The address or the value of the registers is get from this function. So the bug is inside thie function. I check the asm code of "#3 <signal handler called>": (gdb) frame 3 (gdb) p $pc $1 = (void (*)()) 0x7f931fa4d0 (gdb) disassemble $pc, +10 Dump of assembler code from 0x7f931fa4d0 to 0x7f931fa4da: => 0x0000007f931fa4d0: mov x8, #0x8b // #139 0x0000007f931fa4d4: svc #0x0 0x0000007f931fa4d8: nop This is the syscall sys_rt_sigreturn, Linux kernel function "restore_sigframe" will set the frame: for (i = 0; i < 31; i++) __get_user_error(regs->regs[i], &sf->uc.uc_mcontext.regs[i], err); __get_user_error(regs->sp, &sf->uc.uc_mcontext.sp, err); __get_user_error(regs->pc, &sf->uc.uc_mcontext.pc, err); The struct of uc_mcontext is: struct sigcontext { __u64 fault_address; /* AArch64 registers */ __u64 regs[31]; __u64 sp; __u64 pc; __u64 pstate; /* 4K reserved for FP/SIMD state and future expansion */ __u8 __reserved[4096] __attribute__((__aligned__(16))); }; But in GDB function "aarch64_linux_sigframe_init", the code the get address of registers is: for (i = 0; i < 31; i++) { trad_frame_set_reg_addr (this_cache, AARCH64_X0_REGNUM + i, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + i * AARCH64_SIGCONTEXT_REG_SIZE); } trad_frame_set_reg_addr (this_cache, AARCH64_FP_REGNUM, fp); trad_frame_set_reg_addr (this_cache, AARCH64_LR_REGNUM, fp + 8); trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, fp + 8); The code that get pc and sp is not right, so I change the code according to Linux kernel code: trad_frame_set_reg_addr (this_cache, AARCH64_SP_REGNUM, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + 31 * AARCH64_SIGCONTEXT_REG_SIZE); trad_frame_set_reg_addr (this_cache, AARCH64_PC_REGNUM, sigcontext_addr + AARCH64_SIGCONTEXT_XO_OFFSET + 32 * AARCH64_SIGCONTEXT_REG_SIZE); The issue was fixed by this change, and I did the regression test.

1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar manner to the way _GLOBAL_OFFSET_TABLE_ is handled. It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections.

2014-05-19fix two latent type errorsTom Tromey3-4/+7
I'm checking this in as obvious. I was looking at instances of "alloc.*sizeof" and noticed a couple where the types in question are incorrect. In gdbtypes, the code allocates sizeof(int) to represent a struct rank. In mi-cmds, the code uses "struct mi_cmd **" -- one "*" too many. In both cases the problems are latent because in practice the sizes are the same as the sizes of the correct types. Still, it's better to be correct. I think gdb would be improved by a wholesale change from explicit sizeofs to using the libiberty.h allocation macros. In most cases they are both shorter and have better type safety. However, the resulting patch is rather large.
