* system.c [LINUX]: Define CTL_PROC, since Linux 2.6.18+ headers
removed CTL_PROC enum. Patch from Jakub Jelinek.
[LINUX] (sysctl_root): Add CTL_BUS, CTL_ABI and CTL_CPU.
* strace.c [!USE_PROCFS] (trace): Presence of PT_GETSIGINFO
macro does not mean that PT_CR_IPSR and PT_CR_IIP macros are
also defined, so check them along with PT_GETSIGINFO.
Fixes RH#209856.
Fix race conditions in tcb allocation.
* process.c (fork_tcb): Return error code as documented. Do not
print "tcb table full" error message.
[USE_PROCFS] (internal_fork): Do not print "tcb table full"
error message.
[SYS_clone || SYS_clone2] (internal_clone, internal_fork): Call
fork_tcb() before alloctcb(). Do not print "tcb table full"
error message.
* strace.c (main): Do not print "tcb table full" error message.
(expand_tcbtab): Print error message in case of memory allocation
failure.
(alloctcb): Print error message when tcb table is full.
(trace): Expand tcb table if necessary prior to allocating
entry there. Do not print "tcb table full" error message.
Fixes RH#180293.
* system.c [LINUX] (MS_MGC_VAL): New macro.
[LINUX] (mount_flags): Add it.
[LINUX] (sys_mount): If neither MS_BIND nor MS_MOVE bits are
set in the flags argument, try to fetch data string.
Fixes RH#165377.
* defs.h [LINUXSPARC] (PERSONALITY0_WORDSIZE, PERSONALITY1_WORDSIZE):
New macros.
[SPARC64] (PERSONALITY2_WORDSIZE): New macro.
[X86_64] (PERSONALITY0_WORDSIZE, PERSONALITY1_WORDSIZE): New macros.
* syscall.c (PERSONALITY0_WORDSIZE): New macro if undefined.
(personality_wordsize): New variable.
(decode_subcall): Use it for size of argument words.
Fixes RH#174354.
Implement qual_flags support for each personality.
* strace.c (main): Move qualify calls after set_personality call.
* syscall.c (qual_flags0): New variable..
[SUPPORTED_PERSONALITIES >= 2] (qual_flags1): New variable.
[SUPPORTED_PERSONALITIES >= 3] (qual_flags2): New variable.
(qual_flags): Change variable definition from array to pointer.
(set_personality): Initialize qual_flags variable.
(qualify_one): Add "pers" argument to specify personality.
[SUPPORTED_PERSONALITIES >= 2]: Set qual_flags1 if requested.
[SUPPORTED_PERSONALITIES >= 3]: Set qual_flags2 if requested.
(qual_syscall): Pass personality to qualify_one.
[SUPPORTED_PERSONALITIES >= 2]: Look for syscall also in sysent1
table.
[SUPPORTED_PERSONALITIES >= 3]: Look for syscall also in sysent2
table.
(qual_signal): Pass personality to qualify_one.
(qual_desc): Likewise.
(qualify): Use qualify_one instead of manual qual_flags
manipulations.
[SUPPORTED_PERSONALITIES >= 2]: Look for syscall also in sysent1
table.
[SUPPORTED_PERSONALITIES >= 3]: Look for syscall also in sysent2
table.
* defs.h: Update qual_flags declaration.
Fixes RH#173986.
