| 2024-10-10 | gdb/gdbserver: change shared set_tdesc_osabi to take gdb_osabi | Andrew Burgess | 1 | -1/+2 | |
| There is a single declaration of set_tdesc_osabi that is shared between gdbserver/ and gdb/, this declaration takes a 'const char *' argument which is the string representing an osabi. Then in gdb/ we have an overload of set_tdesc_osabi which takes an 'enum gdb_osabi'. In this commit I change the shared set_tdesc_osabi to be the version which takes an 'enum gdb_osabi', and I remove the version which takes a 'const char *'. All users of set_tdesc_osabi are updated to pass an 'enum gdb_osabi'. The features/ code, which is generated from the xml files, requires a new function to be added to osabi.{c,h} which can return a string representation of an 'enum gdb_osabi'. With that new function in place the features/ code is regenerated. This change is being made to support the next commit. In the next commit gdbserver will be updated to call set_tdesc_osabi in more cases. The problem is that gdbserver stores the osabi as a string. The issue here is that a typo in the gdbserver/ code might go unnoticed and result in gdbserver sending back an invalid osabi string. To fix this we want gdbserver to pass an 'enum gdb_osabi' to the set_tdesc_osabi function. With that requirement in place it seems to make sense if all calls to set_tdesc_osabi pass an 'enum gdb_osabi'. There should be no user visible changes after this commit.

| 2024-09-25 | gdb, gdbserver, python, testsuite: Remove MPX. | Schimpe, Christina | 1 | -8/+0 | |
| GDB deprecated the commands "show/set mpx bound" in GDB 15.1, as Intel listed Intel(R) Memory Protection Extensions (MPX) as removed in 2019. MPX is also deprecated in gcc (since v9.1), the linux kernel (since v5.6) and glibc (since v2.35). Let's now remove MPX support in GDB completely. This includes the removal of: - MPX functionality including register support - deprecated mpx commands - i386 and amd64 implementation of the hooks report_signal_info and get_siginfo_type - tests - and pretty printer. We keep MPX register numbers to not break compatibility with old gdbservers. Approved-By: Felix Willgerodt <felix.willgerodt@intel.com> | |||||
| 2024-05-07 | gdb/arch: assert that X86_XSTATE_MPX is not set for x32 | Andrew Burgess | 1 | -2/+6 | |
| While rebasing this series[1] past this commit: commit 4bb20a6244b7091a9a7a2ae35dfbd7e8db27550a Date: Wed Mar 20 04:13:18 2024 -0700 gdbserver: Clear X86_XSTATE_MPX bits in xcr0 on x32 I worried that there could be other paths that might result in an xcr0 value which has X86_XSTATE_MPX set in x32 mode. As everyone eventually calls amd64_create_target_description to build their target description, I figured we could assert in here that if X86_XSTATE_MPX is set then we should not be an x32 target, this will uncover any other bugs in this area. I'm not currently able to build/run any x32 binaries, so I have no way to test this, but the author of commit 4bb20a6244b7091 did test this series with that assert in place and didn't see any problems.

| 2024-01-12 | Update copyright year range in header of all files managed by GDB | Andrew Burgess | 1 | -1/+1 | |
| This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them. | |||||

| 2019-07-09 | Rename common to gdbsupport | Tom Tromey | 1 | -2/+2 | |
| This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

| This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. | |||||
| 2018-06-29 | x86_64-windows GDB crash due to fs_base/gs_base registers | Pedro Alves | 1 | -3/+6 | |
| GDB is currently crashing anytime we try to access the fs_base/gs_base registers, either to read them, or to write them. This can be observed under various scenarios: - Explicit reference to those registers (eg: print $fs_base) -- probably relatively rare; - Calling a function in the inferior, with the crash happening because we are trying to read those registers in order to save their value ahead of making the function call; - Just a plain "info registers"; The crash was introduced by the following commit: | commit 48aeef91c248291dd03583798904612426b1f40a | Date: Mon Jun 26 18:14:43 2017 -0700 | Subject: Include the fs_base and gs_base registers in amd64 target descriptions. The Windows-nat implementation was unfortunately not prepared to deal with those new registers. In particular, the way it fetches registers is done by using a table where the index is the register number, and the value at that index is the offset in the area in the thread's CONTEXT data where the corresponding register value is stored. For instance, in amd64-windows-nat.c, we can find the mappings static array containing the following 57 elements in it: #define context_offset(x) (offsetof (CONTEXT, x)) static const int mappings[] = { context_offset (Rax), [...] context_offset (FloatSave.MxCsr) }; That array is then used by windows_fetch_one_register via: char *context_offset = ((char *) &th->context) + mappings[r]; The problem is that fs_base's register number is 172, which is well past the end of the mappings array (57 elements in total). We end up getting an undefined offset, which happens to be so large that it then causes the address where we try to read the register value (a little bit later) to be invalid, thus crashing GDB with a SEGV. This patch side-steps the issue entirely by removing support for those registers in GDB on x86_64-windows, because a look at the CONTEXT structure indicates no support for getting those registers. A more comprehensive fix would patch the potential buffer overflow of the mappings array, but this can be done as a separate commit. gdb/ChangeLog: * gdb/amd64-tdep.h (amd64_create_target_description): Add "segments" parameter. * gdb/amd64-tdep.c (amd64_none_init_abi, amd64_x32_none_init_abi) (_initialize_amd64_tdep): Update call to amd64_create_target_description.
