--- Comment #7 from Mark Wielaard <m...@klomp.org> --- (In reply to Mark Wielaard from comment #6) > This looks similar to what is reported against Fedora arm64: > https://bugzilla.redhat.com/show_bug.cgi?id=1909548 It isn't exactly the same issue. But related. The issue in that bug is that syswrap-linux.c calls generic_PRE_sys_shmctl and generic_POST_sys_shmctl with an extra VKI_IPC_64 only for amd64_linux, but not for arm64_linux. In both cases (and riscv, but we don't have a port for that) the VKI_IPC_64 is implied. The fix for that is simply: diff --git a/coregrind/m_syswrap/syswrap-linux.c b/coregrind/m_syswrap/syswrap-linux.c index 328e02a98..52074149d 100644 --- a/coregrind/m_syswrap/syswrap-linux.c +++ b/coregrind/m_syswrap/syswrap-linux.c @@ -5127,7 +5127,7 @@ PRE(sys_shmctl) PRINT("sys_shmctl ( %ld, %ld, %#" FMT_REGWORD "x )", SARG1, SARG2, ARG3); PRE_REG_READ3(long, "shmctl", int, shmid, int, cmd, struct shmid_ds *, buf); -#ifdef VGP_amd64_linux +#if defined(VGP_amd64_linux) || defined(VGP_arm64_linux) ML_(generic_PRE_sys_shmctl)(tid, ARG1,ARG2|VKI_IPC_64,ARG3); #else ML_(generic_PRE_sys_shmctl)(tid, ARG1,ARG2,ARG3); @@ -5136,7 +5136,7 @@ PRE(sys_shmctl) POST(sys_shmctl) { -#ifdef VGP_amd64_linux +#if defined(VGP_amd64_linux) || defined(VGP_arm64_linux) ML_(generic_POST_sys_shmctl)(tid, RES,ARG1,ARG2|VKI_IPC_64,ARG3); #else ML_(generic_POST_sys_shmctl)(tid, RES,ARG1,ARG2,ARG3); Then the generic PRE/POST do the right thing selecting the correct data structure size. -- You are receiving this mail because: You are watching all bug changes.
