support: Add support_socket_so_timestamp_time64
|
||||
|
||||
Check if the socket support 64-bit network packages timestamps
|
||||
(SO_TIMESTAMP and SO_TIMESTAMPNS). This will be used on recvmsg
|
||||
and recvmmsg tests to check if the timestamp should be generated.

linux: Fix ancillary 64-bit time timestamp conversion (BZ #28349, BZ#28350)
|
||||
|
||||
The __convert_scm_timestamps only updates the control message last
|
||||
pointer for SOL_SOCKET type, so if the message control buffer contains
|
||||
multiple ancillary message types the converted timestamp one might
|
||||
overwrite a valid message.
|
||||
|
||||
The test checks if the extra ancillary space is correctly handled
|
||||
by recvmsg/recvmmsg, where if there is no extra space for the 64-bit
|
||||
time_t converted message the control buffer should be marked with
|
||||
MSG_TRUNC. It also check if recvmsg/recvmmsg handle correctly multiple
|
||||
ancillary data.
|
||||
|
||||
Checked on x86_64-linux and on i686-linux-gnu on both 5.11 and
|
||||
4.15 kernel.

Linux: Only generate 64 bit timestamps for 64 bit time_t recvmsg/recvmmsg
|
||||
|
||||
The timestamps created by __convert_scm_timestamps only make sense for
|
||||
64 bit time_t programs, 32 bit time_t programs will ignore 64 bit time_t
|
||||
timestamps since SO_TIMESTAMP will be defined to old values (either by
|
||||
glibc or kernel headers).
|
||||
|
||||
Worse, if the buffer is not suffice MSG_CTRUNC is set to indicate it
|
||||
(which breaks some programs [1]).
|
||||
|
||||
This patch makes only 64 bit time_t recvmsg and recvmmsg to call
|
||||
__convert_scm_timestamps. Also, the assumption to called it is changed
|
||||
from __ASSUME_TIME64_SYSCALLS to __TIMESIZE != 64 since the setsockopt
|
||||
might be called by libraries built without __TIME_BITS=64. The
|
||||
MSG_CTRUNC is only set for the 64 bit symbols, it should happen only
|
||||
if 64 bit time_t programs run older kernels.
|
||||
|
||||
Checked on x86_64-linux-gnu and i686-linux-gnu.

tst-socket-timestamp-compat.c: Check __TIMESIZE [BZ #28837]
|
||||
|
||||
time_t size is defined by __TIMESIZE, not __WORDSIZE. Check __TIMESIZE,
|
||||
instead of __WORDSIZE, for time_t size. This fixes BZ #28837.
