Subject: [Bug tdep/30540] New: [gdb/tdep] AT_RSEQ_FEATURE_SIZE / AT_RSEQ_ALIGN support missing in "info auxv"
Date: Mon, 12 Jun 2023 07:36:57 +0000 [thread overview]
Message-ID: <bug-30540-4717@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=30540
Bug ID: 30540
Summary: [gdb/tdep] AT_RSEQ_FEATURE_SIZE / AT_RSEQ_ALIGN
support missing in "info auxv"
Product: gdb
Version: 13.1
Status: NEW
Severity: normal
Priority: P2
Component: tdep
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
With a 13.2 based packaged, on openSUSE Tumbleweed x86_64, I run into:
...
(gdb) info auxv^M
33 AT_SYSINFO_EHDR System-supplied DSO's ELF header 0x7ffff7fc7000^M
51 AT_MINSIGSTKSZ Minimum stack size for signal delivery 0x6f0^M

15 AT_PLATFORM String identifying platform 0x7fffffffdab9

...
Grepping in the kernel sources gets me:
...
$ find -name auxvec.h | xargs grep 27
./include/uapi/linux/auxvec.h:#define AT_RSEQ_FEATURE_SIZE 27 /* rseq
supported feature size */
$ find -name auxvec.h | xargs grep 28
./include/uapi/linux/auxvec.h:#define AT_RSEQ_ALIGN 28 /* rseq
allocation alignment */
...
