Well, here's more SVR4 woes, on sparc architecture with Solaris 2.5.1 bins.
Firstly, the auditsys syscall is unimplemented and breaks with a
psignal(p,SIGSYS). Could this fail quietly with SVR4_ENOSYS, or do we know
too little to let the call pass? It makes some programs fail in rather
Secondly, can someone pull up src/sys/compat/svr4/svr4_misc.c from trunk
into 1.3 branch? (Are trunk pullups being done at all?) It fixes the
problem I posted last about getdents.
Thirdly, and the subject line of this post; it seems some Solaris programs
(pkginstall in particular) are trying to "truncate" a file via fcntl.
In the partial ktrace here, pkginstall (a subprocess of pkgadd) is opening a
file in a mock Solaris root tree, which works fine. The fcntl here fails,
though, and I can't see whats returning errno 89:
1160 pkginstall CALL open(0xefffd860,0x1,0)
1160 pkginstall NAMI "/emul/svr4/emul/svr4new/var/sadm/install/t.contents"
1160 pkginstall NAMI "/emul/svr4new/var/sadm/install/t.contents"
1160 pkginstall RET open 10/0xa
1160 pkginstall CALL fcntl(0xa,0xb,0xefffd77c)
1160 pkginstall RET fcntl -1 errno 89 Unknown error: 89
1160 pkginstall CALL close(0xa)
1160 pkginstall RET close 0
1160 pkginstall CALL write(0x2,0x4fe08,0x6)
1160 pkginstall GIO fd 2 wrote 6 bytes
1160 pkginstall RET write 6
1160 pkginstall CALL write(0x2,0x33db6,0x9)
1160 pkginstall GIO fd 2 wrote 9 bytes
": ERROR: "
1160 pkginstall RET write 9
1160 pkginstall CALL write(0x2,0x2f5b8,0x2a)
1160 pkginstall GIO fd 2 wrote 42 bytes
"unable to truncate temporary contents file"
