Subject: [PATCH 158/162] tests: disable TEST_MSGCTL_BOGUS_ADDR in ipc_msg test
|
|
|
6f827f |
on glibc >= 2.31
|
|
|
6f827f |
|
|
|
6f827f |
Starting with commit glibc-2.31~358, on every architecture where
|
|
|
6f827f |
__ASSUME_SYSVIPC_BROKEN_MODE_T is defined, glibc tries to modify the
|
|
|
6f827f |
data provided in the third argument of msgctl call. This results
|
|
|
6f827f |
to segfaults inside glibc if TEST_MSGCTL_BOGUS_ADDR is enabled.
|
|
|
6f827f |
|
|
|
6f827f |
* tests/ipc_msg.c [GLIBC_PREREQ_GE(2, 31) && (__m68k__ || __s390__ ||
|
|
|
6f827f |
(WORDS_BIGENDIAN && (__arm__ || __microblaze__ || __sh__)))]
|
|
|
6f827f |
(TEST_MSGCTL_BOGUS_ADDR): Define to 0.
