17 hoursgdb: update corner case when canonicalizing riscv syscall namesGuinevere Larsen1-1/+1
The script syscalls/riscv-canonicalize-syscall-gen.py has been recently introduced to help support record-full in riscv systems. However, it was developed before commit 432eca4113d5748ad284a068873455f9962b44fe, which made the GDB enum more consistent, which forced the python script to have a corner case for the "gdb_old_mmap" case. Since the aforementioned commit has already been merged, we need to update the special case for the mmap syscall. A special case is still needed because the script would expect that the glibc sources call the syscall "old_mmap", or that gdb call it "gdb_sys_mmap", neither of which happens unfortunately. This commit doesn't change the .c file because it was already fixed by a different commit, 65ab41b7d5c612b6000b28f4c50bb256b2a9e22b, which was pushed as obvious to fix the build issues.

When I (Guinevere) pushed commit b9c7eed0c2409fc640129a38d80a2bf1212b464a I accidentally used an outdated version of the patch. This current patch fixes the importation of that patch based on the actually approved version instead.
47 hoursThis commit adds record full support for rv64gc instruction setTimur1-0/+163
It includes changes to the following files: - gdb/riscv-linux-tdep.c, gdb/riscv-linux-tdep.h: adds facilities to record syscalls. - gdb/riscv-tdep.c, gdb/riscv-tdep.h: adds facilities to record execution of rv64gc instructions. - gdb/configure.tgt: adds new files for compilation. - gdb/testsuite/lib/gdb.exp: enables testing of full record mode for RISC-V targets. - gdb/syscalls/riscv-canonicalize-syscall-gen.py: a script to generate function that canonicalizes RISC-V syscall. This script can simplify support for syscalls on rv32 and rv64 system (currently support only for rv64). To use this script you need to pass a path to a file with syscalls description from riscv-glibc (example is in the help message). The script produces a mapping from syscall names to gdb_syscall enum. - gdb/riscv-canonicalize-syscall.c: the file generated by the previous script. - gdb/doc/gdb.texinfo: notification that record mode is enabled in RISC-V. - gdb/NEWS: notification of new functionality.

In gdb commit a08dc2aa004b ("gdb: syscalls: Add loongarch-linux.xml.in"), we find: There exist some __NR3264_ prefixed syscall numbers, replace them with digital numbers according to /usr/include/asm-generic/unistd.h and sort them by syscall number manually, maybe we can modify the script to do it automatically in the future. It is time to do it now, just handle __NR3264_ prefixed syscall number automatically in the script update-linux.sh. By the way, a Linux kernel patch did the similar change [1].

2024-12-09[gdb/syscalls] Generate aarch64-linux.xml.in in update-linux-from-src.shTom de Vries2-2/+50
Currently aarch64-linux.xml.in is skipped by update-linux-from-src.sh: ... $ ./update-linux-from-src.sh ~/upstream/linux-stable.git/ Skipping aarch64-linux.xml.in, no syscall.tbl ... $ ... and instead we use update-linux.sh. This works fine, but requires an aarch64 system with recent system headers, which makes it harder to pick up the latest changes in the linux kernel. Fix this by updating ./update-linux-from-src.sh to: - build the linux kernel headers for aarch64 - use update-linux.sh with those headers to generate aarch64-linux.xml.in. Regenerating aarch64-linux.xml.in using current trunk of linux-stable gives me these changes: ... + <syscall name="setxattrat" number="463"/> + <syscall name="getxattrat" number="464"/> + <syscall name="listxattrat" number="465"/> + <syscall name="removexattrat" number="466"/> ... which are the same changes I see for the other architectures. Note that the first step, building the linux kernel headers is a cross build and should work on any architecture. But the second step, update-linux.sh uses plain gcc rather than a cross-gcc, so there is scope for problems, but we seem to get away with this on x86_64-linux. So, while we could constrain this to only generate aarch64-linux.xml.in on aarch64-linux, I'm leaving this unconstrained. For aarch64-linux.xml.in, this doesn't matter much to me because I got an aarch64-linux system. But I don't have a longaarch system, and the same approach seems to work there. I'm leaving this for follow-up patch though. Tested on aarch64-linux and x86_64-linux. Verified with shellcheck.

In commit 58776901074 ("[gdb/syscalls] Update to linux v6.11") I updated to linux v6.11, but a recent submission for loongarch [1] used a current trunk version, so it makes sense to do this as well elsewhere. Using linux current trunk with update-linux-from-src.sh gets us 4 more syscalls: - setxattrat - getxattrat - listxattrat - removexattrat Tested on x86_64-linux.

2024-11-26[gdb/syscalls] Use update-linux-from-src.sh for arm-linuxTom de Vries4-85/+235
I tried to use arm-linux.py to regenerate arm-linux.xml.in, but it didn't work.

In commit a08dc2aa004b (gdb: syscalls: Add loongarch-linux.xml.in), it needs special handling when generating xml file. This should at least be mentioned in the file comment rather than git log to help the next person who regenerates this file understand what needs to be done, suggested by Pedro Alves, thank you. At the beginning, I only added the tips in loongarch-linux.xml.in, after executing the command "make" to generate loongarch-linux.xml from loongarch-linux.xml.in, it generates the same tips in the file loongarch-linux.xml automatically, so update loongarch-linux.xml.in and loongarch-linux.xml together.

2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess40-41/+41
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.

2023-02-27Regenerate Linux syscall group infoPedro Alves15-856/+1001
This commit makes use of the new script to regenerate the Linux syscall group info against strace git hash e88e5e9ae6da68f22d15f9be3193b1412ac9aa02. Like so: $ cd gdb/syscalls/ $ ./update-linux-defaults.sh ~/strace.git/ Generating linux-defaults.xml.in $ make for f in aarch64-linux.xml amd64-linux.xml arm-linux.xml bfin-linux.xml \ i386-linux.xml mips-n32-linux.xml mips-n64-linux.xml \ mips-o32-linux.xml ppc64-linux.xml ppc-linux.xml s390-linux.xml \ s390x-linux.xml sparc64-linux.xml sparc-linux.xml; do \ xsltproc --output $f apply-defaults.xsl $f.in; \ done The result is that a lot more syscalls end up assigned to groups.

2023-02-27Autogenerate gdb/syscalls/linux-defaults.xml.in (groups) from strace sourcesPedro Alves1-0/+91
I noticed that "catch syscall group:process" doesn't catch clone3, while it does catch clone. The catch syscall group information is recorded in the gdb/syscalls/linux-defaults.xml.in file, which says: <!-- The group field information was based on strace. --> So I looked at the strace sources, to confirm that clone3 is in fact recorded in the "process" group there too, and to check what other syscalls might be missing groups. After some digging, I found that strace records the group info in C arrays, with entries like: ... [ 61] = { 4, TP, SEN(wait4), "wait4" }, [ 62] = { 2, TS|TP, SEN(kill), "kill" }, [ 63] = { 1, 0, SEN(uname), "uname" }, ... You can see the current master's table for Linux x86-64 here: https://github.com/strace/strace/blob/e88e5e9ae6da68f22d15f9be3193b1412ac9aa02/src/linux/x86_64/syscallent.h The column with TS|TP above is what defines each syscall's groups. So I wrote a script that extracts this information and generates linux-defaults.xml.in. Approved-By: Simon Marchi <simon.marchi@efficios.com> Change-Id: I679d59d42fb2a914bf7a99e4c558e9696e5adff1
2023-01-01manual copyright year range of various GDB files to add 2023Joel Brobecker1-1/+1
This commit updates the following file... gdb/doc/gdb.texinfo gdb/doc/refcard.tex gdb/syscalls/update-netbsd.sh ... by hand as instructed by the gdb/copyright.py script. The update by hand is needed because the copyright headers to update are actually nested inside those files, rather than located at the start of the file.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker39-39/+39
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-05-18[gdb/tdep] Add gdb/syscalls/update-linux-from-src.shTom de Vries23-38/+1230
Add a new script gdb/syscalls/update-linux-from-src.sh, that can be used to generate *-linux.xml.in files from linux kernel sources, like so: ... $ ./update-linux-from-src.sh ~/upstream/linux-stable.git Skipping aarch64-linux.xml.in, no syscall.tbl Generating amd64-linux.xml.in Skipping arm-linux.xml.in, use arm-linux.py instead Skipping bfin-linux.xml.in, no longer supported Generating i386-linux.xml.in Generating mips-n32-linux.xml.in Generating mips-n64-linux.xml.in Generating mips-o32-linux.xml.in Generating ppc64-linux.xml.in Generating ppc-linux.xml.in Generating s390-linux.xml.in Generating s390x-linux.xml.in Generating sparc64-linux.xml.in Generating sparc-linux.xml.in ... Update *-linux.xml.in and *-linux.xml using linux kernel tag v5.18-rc6.
2022-05-12[gdb/tdep] Improve gdb/syscalls/update-linux.shTom de Vries2-42/+23
Fix two things in update-linux.sh: - remove use of unnecessary tmp file - inline gen-header.py into update-linux.sh Tested on x86_64-linux.
2022-05-11[gdb/tdep] Update syscalls/{ppc64,ppc}-linux.xmlTom de Vries4-22/+538
Regenerate syscalls/{ppc64,ppc}-linux.xml on a system with 5.14 kernel.
2022-05-09[gdb] Update syscalls/{amd64,i386}-linux.xmlTom de Vries6-14/+470
- Add a script syscalls/gen-header.py, based on syscalls/arm-linux.py. - Add a script syscalls/update-linux.sh (alongside update-freebsd.sh and update-netbsd.sh). - Use syscalls/update-linux.sh to update syscalls/{amd64,i386}-linux.xml.in. - Regenerate syscalls/{amd64,i386}-linux.xml using syscalls/Makefile. In gdb/syscalls/i386-linux.xml.in, updating has the following notable effect: ... - <syscall name="madvise1" number="220"/> - <syscall name="getdents64" number="221"/> - <syscall name="fcntl64" number="222"/> + <syscall name="getdents64" number="220"/> + <syscall name="fcntl64" number="221"/> ... I've verified in ./arch/x86/entry/syscalls/syscall_32.tbl that the numbers are correct. Tested on x86_64-linux.
2022-05-09[gdb] Add gdb/syscalls/MakefileTom de Vries2-0/+348
Add a Makefile in gdb/syscalls that can be used to translate gdb/syscalls/*.xml.in into gdb/syscalls/*.xml. Calling make reveals that bfin-linux.xml is missing, so add it. Tested on x86_64-linux.
2022-05-09[gdb/tdep] Support catch syscall pipe2 for i386Tom de Vries2-0/+2
With test-case gdb.base/catch-syscall.exp and target board unix/-m32, we run into: ... (gdb) catch syscall pipe2^M Unknown syscall name 'pipe2'.^M (gdb) FAIL: gdb.base/catch-syscall.exp: determine pipe syscall: catch syscall pipe2 ... Fix this by: - adding a pipe2 entry in gdb/syscalls/i386-linux.xml.in, and - regenerating gdb/syscalls/i386-linux.xml using "xsltproc --output i386-linux.xml apply-defaults.xsl i386-linux.xml.in". Tested on x86_64-linux with native and unix/-m32. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29056

2021-05-07gdb: re-format Python files using black 21.4b0Simon Marchi1-13/+16
Re-format all Python files using black [1] version 21.4b0. The goal is that from now on, we keep all Python files formatted using black. And that we never have to discuss formatting during review (for these files at least) ever again. One change is needed in gdb.python/py-prettyprint.exp, because it matches the string representation of an exception, which shows source code. So the change in formatting must be replicated in the expected regexp. To document our usage of black I plan on adding this to the "GDB Python Coding Standards" wiki page [2]: --8<-- All Python source files under the `gdb/` directory must be formatted using black version 21.4b0. This specific version can be installed using: $ pip3 install 'black == 21.4b0' All you need to do to re-format files is run `black <file/directory>`, and black will re-format any Python file it finds in there. It runs quite fast, so the simplest is to do: $ black gdb/ from the top-level. If you notice that black produces changes unrelated to your patch, it's probably because someone forgot to run it before you. In this case, don't include unrelated hunks in your patch. Push an obvious patch fixing the formatting and rebase your work on top of that. -->8-- Once this is merged, I plan on setting a up an `ignoreRevsFile` config so that git-blame ignores this commit, as described here: https://github.com/psf/black#migrating-your-code-style-without-ruining-git-blame I also plan on working on a git commit hook (checked in the repo) to automatically check the formatting of the Python files on commit. [1] https://pypi.org/project/black/ [2] https://sourceware.org/gdb/wiki/Internals%20GDB-Python-Coding-Standards gdb/ChangeLog: * Re-format all Python files using black. gdb/testsuite/ChangeLog: * Re-format all Python files using black. * gdb.python/py-prettyprint.exp (run_lang_tests): Adjust.
