2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+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.
2023-11-21gdb: Replace gdb::optional with std::optionalLancelot Six1-2/+2
Since GDB now requires C++17, we don't need the internally maintained gdb::optional implementation. This patch does the following replacing: - gdb::optional -> std::optional - gdb::in_place -> std::in_place - #include "gdbsupport/gdb_optional.h" -> #include <optional> This change has mostly been done automatically. One exception is gdbsupport/thread-pool.* which did not use the gdb:: prefix as it already lives in the gdb namespace.

2023-10-04sme2: Enable SME2 support in gdbserverLuis Machado1-0/+57
This patch teaches gdbserver about the SME2 and the ZT0 register. Since most of the code used by gdbserver for SME2 is shared with gdb, this is a rather small patch that reuses most of the code put in place for native AArch64 Linux. Validated under Fast Models.

2023-10-04sme: Add support for SMELuis Machado1-0/+60
Enable SME support in gdbserver by adjusting the usual fields. There is not much to this patch because the code is either in gdb or it is shared between gdbserver and gdb. One exception is the bump to gdbserver's PBUFSIZ from 18432 to 131104. Since the ZA register can be quite big (256 * 256 bytes), the g/G remote packet will also become quite big From gdbserver/tdesc.cc:init_target_desc, I estimated the new size should be at least (2 * 256 * 256 + 32), which yields 131104. It is also unlikely we will find a process starting up with SVL set to 256. Ideally we'd adjust the packet size dynamically based on what we need, but for now this should do. Please note we have the same limitation for SME that we have for SVE, and that is the fact gdbserver cannot communicate vector length changes to gdb via the remote protocol. Thiago is working on this improvement, which hopefully will be able to be adapted to SME in an easy way.

2023-10-04refactor: Simplify SVE interface to read/write registersLuis Machado1-3/+21
This is a patch in preparation to upcoming patches enabling SME support. It attempts to simplify the gdb/gdbserver shared interface used to read/write SVE registers. Where the current code makes use of unique_ptr, allocating a new buffer by hand and passing a buffer around, this patch makes that code use gdb::byte_vector and passes a reference to this byte vector to the functions, allowing the functions to have ready access to the size of the buffer. It also shares a bit more code between gdb and gdbserver, in particular around handling of ptrace get/set requests for SVE. I think gdbserver could be refactored to handle register reads/writes more like gdb's native layer as opposed to letting the generic linux-low layer do the ptrace calls. This is not very flexible and assumes one size for the responses. If you have something like NT_ARM_SVE, where you can have either FPSIMD or SVE contents, it doesn't work that well. I didn't want to change that interface right now as it is a bit too much work and touches all the targets, some of which I can't easily test. Hence the reason why the buffer the generic linux-now passes down to linux-aarch64-low is unused or ignored. No user-visible changes should happen as part of this refactor other than a slightly reworded warning message. While doing the refactor, I also noticed what seems to be a mistake in checking if the register cache contains active (non-zero) SVE data. For instance, the original code did something like this in aarch64_sve_regs_copy_from_reg_buf: has_sve_state |= reg_buf->raw_compare (AARCH64_SVE_Z0_REGNUM + i reg, sizeof (__int128_t)); "reg" is a zeroed-out buffer that we compare the Z register contents past the first 128 bits. The problem here is that raw_compare returns 1 if the contents compare the same, which means has_sve_state will be true. But if we compared the Z register contents to 0, it means we *do not* have SVE state, and therefore has_sve_state should be false. The consequence of this mistake is that we convert the initial FPSIMD-formatted data we get from ptrace for the NT_ARM_SVE register set to a SVE-formatted one. In the end, this doesn't cause user-visible differences because the values of both the Z and V registers will still be the same. But the logic is not correct. I used the opportunity to fix this, and it gets tested later on by the additional SME tests. I do plan on submitting some SVE-specific tests to make sure we have a bit more coverage in GDB's testsuite. Regression-tested on aarch64-linux Ubuntu 22.04/20.04.

This patch doesn't change gdbserver behaviour, but after later changes are made it avoids a null pointer dereference when HWCAP needs to be obtained for a specific process while current_thread is nullptr. Fixing linux_read_auxv, linux_get_hwcap and linux_get_hwcap2 to take a PID parameter seems more correct than setting current_thread in one particular code path.

2022-12-16[aarch64] Fix removal of non-address bits for PAuthLuis Machado1-12/+21
PR gdb/28947 The address_significant gdbarch setting was introduced as a way to remove non-address bits from pointers, and it is specified by a constant. This constant represents the number of address bits in a pointer. Right now AArch64 is the only architecture that uses it, and 56 was a correct option so far. But if we are using Pointer Authentication (PAuth), we might use up to 2 bytes from the address space to store the required information. We could also have cases where we're using both PAuth and MTE. We could adjust the constant to 48 to cover those cases, but this doesn't cover the case where GDB needs to sign-extend kernel addresses after removal of the non-address bits. This has worked so far because bit 55 is used to select between kernel-space and user-space addresses. But trying to clear a range of bits crossing the bit 55 boundary requires the hook to be smarter. The following patch renames the gdbarch hook from significant_addr_bit to remove_non_address_bits and passes a pointer as opposed to the number of bits. The hook is now responsible for removing the required non-address bits and sign-extending the address if needed. While at it, make GDB and GDBServer share some more code for aarch64 and add a new arch-specific testcase gdb.arch/aarch64-non-address-bits.exp.

2022-12-09[aarch64] Add TPIDR2 register support for LinuxLuis Machado1-5/+19
With the AArch64 Scalable Matrix Extension we have a new TPIDR2 register, and it will be added to the existing NT_ARM_TLS register set. Kernel patches are being reviewed here: https://lore.kernel.org/linux-arm-kernel/20220818170111.351889-1-broonie@kernel.org/ From GDB's perspective, we handle it in a similar way to the existing TPIDR register. But we need to consider cases of systems that only have TPIDR and systems that have both TPIDR and TPIDR2. With that in mind, the following patch adds the required code to support TPIDR2 and turns the org.gnu.gdb.aarch64.tls feature into a dynamically-generated target description as opposed to a static target description containing only TPIDR. That means we can remove the gdb/features/aarch64-tls.xml file and replace the existing gdb/features/aarch64-tls.c auto-generated file with a new file that dynamically generates the target description containing either TPIDR alone or TPIDR and TPIDR2. In the future, when *BSD's start to support this register, they can just enable it as is being done for the AArch64 Linux target. The core file read/write code has been updated to support TPIDR2 as well. On GDBserver's side, there is a small change to the find_regno function to expose a non-throwing version of it. It always seemed strange to me how find_regno causes the whole operation to abort if it doesn't find a particular register name. The patch moves code from find_regno into find_regno_no_throw and makes find_regno call find_regno_no_throw instead. This allows us to do register name lookups to find a particular register number without risking erroring out if nothing is found. The patch also adjusts the feature detection code for aarch64-fbsd, since the infrastructure is shared amongst all aarch64 targets. I haven't added code to support TPIDR2 in aarch64-fbsd though, as I'm not sure when/if that will happen.

In #3, the current thread is nullptr because gdb_read_memory clears it on purpose, via set_desired_process, exactly to expose code relying on the current thread when it shouldn't. It was always possible to end up in this situation (when the current thread exits), but it was harder to reproduce before. This commit fixes it by tweaking is_64bit_tdesc to look at the current process's tdesc instead of the current thread's tdesc. Note that the thread's tdesc is itself filled from the process's tdesc, so this should be equivalent: struct regcache * get_thread_regcache (struct thread_info *thread, int fetch) { struct regcache *regcache; regcache = thread_regcache_data (thread); ... if (regcache == NULL) { struct process_info *proc = get_thread_process (thread); gdb_assert (proc->tdesc != NULL); regcache = new_register_cache (proc->tdesc); set_thread_regcache_data (thread, regcache); } ...

2022-03-22nat: Split out platform-independent aarch64 debug register support.John Baldwin1-5/+8
Move non-Linux-specific support for hardware break/watchpoints from nat/aarch64-linux-hw-point.c to nat/aarch64-hw-point.c. Changes beyond a simple split of the code are: - aarch64_linux_region_ok_for_watchpoint and aarch64_linux_any_set_debug_regs_state renamed to drop linux_ as they are not platform specific. - Platforms must implement the aarch64_notify_debug_reg_change function which is invoked from the platform-independent code when a debug register changes for a given debug register state. This does not use the indirection of a 'low' structure as is done for x86. - The handling for kernel_supports_any_contiguous_range is not pristine. For non-Linux it is simply defined to true. Some uses of this could perhaps be implemented as new 'low' routines for the various places that check it instead? - Pass down ptid into aarch64_handle_breakpoint and aarch64_handle_watchpoint rather than using current_lwp_ptid which is only defined on Linux. In addition, pass the ptid on to aarch64_notify_debug_reg_change instead of the unused state argument.

Replace uses of the debug_enter and debug_exit macros with THREADS_SCOPED_DEBUG_ENTER_EXIT, which serves essentially the same purpose, but allows showing what comes between the enter and the exit in an indented form. Note that "threads" debug is currently used for a bit of everything in GDBserver, not only threads related stuff. It should ideally be cleaned up and separated logically as is done in GDB, but that's out of the scope of this patch. Change-Id: I2d4546464462cb4c16f7f1168c5cec5a89f2289a

2021-11-03[AArch64] Make gdbserver register set selection dynamicLuis Machado1-85/+101
The current register set selection mechanism for AArch64 is static, based on a pre-populated array of register sets. This means that we might potentially probe register sets that are not available. This is OK if the kernel errors out during ptrace, but probing the tag_ctl register, for example, does not result in a ptrace error if the kernel supports the tagged address ABI but not MTE (PR 28355). Making the register set selection dynamic, based on feature checks, solves this and simplifies the code a bit. It allows us to list all of the register sets only once, and pick and choose based on HWCAP/HWCAP2 or other properties. I plan to backport this fix to GDB 11 as well.

2020-12-16Fix TBI handling for watchpointsLuis Machado1-1/+23
When inserting hw watchpoints, we take care of masking off the top byte of the address (and sign-extending it if needed). This guarantees we won't pass tagged addresses to the kernel via ptrace. However, from the kernel documentation on tagged pointers... "Non-zero tags are not preserved when delivering signals. This means that signal handlers in applications making use of tags cannot rely on the tag information for user virtual addresses being maintained for fields inside siginfo_t. One exception to this rule is for signals raised in response to watchpoint debug exceptions, where the tag information will be preserved." So the stopped data address after a hw watchpoint hit can be potentially tagged, and we don't handle this in GDB at the moment. This results in GDB missing a hw watchpoint hit and attempting to step over an unsteppable hw watchpoint, causing it to spin endlessly. The following patch fixes this by adjusting the stopped data address and adds some tests to expose the problem. gdb/ChangeLog: 2020-12-16 Luis Machado <luis.machado@linaro.org> * aarch64-linux-nat.c (aarch64_linux_nat_target::stopped_data_address): Handle the TBI. gdbserver/ChangeLog: 2020-12-16 Luis Machado <luis.machado@linaro.org> * linux-aarch64-low.cc (address_significant): New function.
