* maint/ioctls_sym.sh: Skip asm/core_*.h. Filter out from
asm-generic/ioctls.h those macros that are defined using unavailable
struct termios2 on alpha and powerpc.
* maint/ioctls_sym.sh: Remove pre-include linux/kvm.h workarounds.
Skip linux/kvm.h on those architectures that have no asm/kvm.h file.
Introduce post-process workarounds, add post-process workarounds
for linux/kvm.h.
Kernel code does this when compares it with -1 (apart from comparing it with
PR_SET_PTRACER_ANY, which is also -1) in security/yama/yama_lsm.c.
* prctl.c (SYS_FUNC(prctl)) <PR_SET_PTRACER>: Cast arg2 to int before
comparing it with -1.
The prctl syscall does not use compat on x32/n32, so argument types
are in fact kernel_ulong_t.
* prctl.c (print_prctl_args): Use getarg_ull, print as "%#llx" instead
of "%#lx".
(SYS_FUNC(prctl)): Use getarg_ull to store call arguments in arg2, arg3,
arg4, arg5 variables of type unsigned long long. Use them in printing
routines.
(SYS_FUNC(arch_prctl)): Use getarg_ull to store call argument in addr
variable of type unsigned long long. Print it as "%#llx" instead of
"%#lx".
This is done in order to fix build error on old distributions where
struct blkpg_ioctl_arg declaration is broken:
In file included from block.c:35:
/usr/include/linux/blkpg.h:36: error: expected ':', ',', ';', '}' or '__attribute__' before '*' token
block.c: In function 'print_blkpg_req':
block.c:113: error: 'struct_blkpg_ioctl_arg' has no member named 'data'
(from SLE10)
* block.c: Include <linux/ioctl.h> instead of <linux/blkpg.h>.
(BLKPG, BLKPG_DEVNAMELTH, BLKPG_VOLNAMELTH): New macros.
(struct_blkpg_ioctl_arg, struct_blkpg_partition): New definitions,
copied from blkpg_ioctl_arg and blkpg_partition structures defined
in <linux/blkpg.h>.
Since UAPI header declares them under CONFIG_CHECKPOINT_RESTORE
and they would never be defined in user space.
* xlat/archvals.in: Add numeric values to ARCH_MAP_VDSO_* constants.
There are no users of prctl function in prctl.c, and all the rest
is provided by <linux/prctl.h> anyway.
* prctl.c: Include <linux/prctl.h> instead of <sys/prctl.h>.
* prctl.c (SYS_FUNC(prctl)): Use printstr_ex with QUOTE_0_TERMINATED
instead of printstr to print the argument of PR_SET_NAME and PR_GET_NAME
operations.
* util.c (printstr_ex): Simplify handling of size == 0 case.
Do not artificially decrement size when QUOTE_0_TERMINATED bit is set.
Ensure that str[size] byte is non-zero if it hasn't been fetched.
When user_style has QUOTE_0_TERMINATED bit set, printstr_ex prints
the fetched string as a NUL-terminated.
After this change, the string is being fetched as a NUL-terminated, too.
* util.c (printstr_ex): Use umovestr instead of umoven
if QUOTE_0_TERMINATED bit is set.
* xlat/v4l2_device_capabilities_flags.in: Add V4L2_CAP_TOUCH introduced
by linux kernel commit v4.9-rc4~7^2~422.
* xlat/v4l2_input_types.in: Add V4L2_CAP_TOUCH introduced
by linux kernel commit v4.9-rc4~7^2~422.
Fix the following build error on SLE 11 SP4:
btrfs.c: In function 'btrfs_test_dev_replace_ioctl':
btrfs.c:1570: error: unknown field 'start' specified in initializer
* tests/btrfs.c (btrfs_test_dev_replace_ioctl): Move initialization
of struct btrfs_ioctl_dev_replace_args.start.srcdevid out of the
designated initializer.
Do not assume that the string returned by signame starts with "SIG"
prefix, this is not always the case.
* syscall.c (qual_signal): Skip signame return value
when it does not have "SIG" prefix.
Change the way how subsequent -e fault= expressions are interpreted
to implement a cumulative behavior. For example,
-e fault=file:when=3+ -e fault=chdir
now specifies that all chdir syscalls and 3+ file related syscalls
except chdir are subject for fault injection.
* syscall.c (qualify): Do not reset qual_vec for QUAL_FAULT.
* tests/fault_injection.test: Check it.
Introduce new -e fault=EXPR syntax that can be used to specify a subset
of syscalls that are subject of syscall fault injection, an error code
that has to be injected, and a frequency of injection.
The expression specifying syscall fault injection has the following
format: SET[:error=ERRNO][:when=FIRST[+[STEP]]]
where only SET is a required part and all the rest is optional.
The method used to implement syscall fault injection is the following:
on entering syscall the syscall number is substituted by an invalid
syscall number -1, and on exiting syscall the error code returned by
the kernel is substituted with the error code specified in the fault
expression.
This implementaion is based on the prototype developed
by Nahim El Atmani as a part of his GSoC 2016 strace project.
* defs.h (struct fault_opts): New forward declaration.
(struct tcb): Add fault_vec field.
(TCB_FAULT_INJ, QUAL_FAULT): New macros.
* strace.1: Document -e fault expression syntax.
* strace.c (usage): Mention -e fault expression.
(droptcb): Deallocate fault_vec member.
* syscall.c (qual_fault, arch_set_scno, arch_set_error): New prototypes.
(qual_options): Add "fault" option.
(struct fault_opts): New structure.
(num_faults): New variable.
(fault_vec): New array.
(syscall_fault_injected, tcb_fault_opts, reallocate_fault,
find_errno_by_name, qual_syscall_ex, strip_prefix, parse_fault_token,
parse_fault_expression, qual_fault, inject_syscall_fault_entering,
update_syscall_fault_exiting): New functions.
(qual_syscall): Use qual_syscall_ex.
(qualify_one): Add argument: a pointer to struct fault_opts, all callers
changed. Copy struct fault_opts from the pointer to fault_vec.
Use reallocate_fault.
(qualify_scno, qualify_syscall_class, qualify_syscall_name): Add
argument: a pointer to struct fault_opts.
(qualify): Use reallocate_fault. Do not check "all" class for
QUAL_FAULT qualifier.
(lookup_class): Check for "all" class.
(trace_syscall_entering): Use inject_syscall_fault_entering.
(trace_syscall_exiting): Use update_syscall_fault_exiting. Clear
TCB_FAULT_INJ flag along with TCB_INSYSCALL. Print " (INJECTED)" suffix
when the syscall has been injected successfully.
[ARCH_REGS_FOR_GETREGSET && !HAVE_GETREGS_OLD]
(ptrace_setregset): New function.
(ptrace_setregset_or_setregs): Define to ptrace_setregset.
[ARCH_REGS_FOR_GETREGS && !HAVE_GETREGS_OLD]
(ptrace_setregs): New function.
(ptrace_setregset_or_setregs): Define to ptrace_setregs.
[ptrace_setregset_or_setregs] (set_regs): New function.
Include "set_scno.c" and "set_error.c"
* NEWS: Mention this enhancement.
The incomplete CRIS support introduced by commit v4.5.18-77-gea0e6e8
should not have been merged because it lacks essential parts, e.g.
syscall tables.
This change adds missing syscall tables for crisv10 and crisv32.
* linux/crisv10/syscallent.h: New file.
* linux/crisv32/syscallent.h: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* defs.h (string_to_uint_ex): New prototype.
(string_to_uint_upto): New function, a thin wrapper around
string_to_uint_ex.
* util.c (string_to_uint_ex): New function.
(string_to_uint): Change into a thin wrapper around string_to_uint_upto.
* strace.c (init): Use string_to_uint_upto.
* syscall.c (qualify_scno, qual_signal, qual_desc): Use
string_to_uint_upto instead of string_to_uint.
Split qual_syscall into qualify_scno, qualify_syscall_class,
and qualify_syscall_name.
This might be needed later to implement syscall fault injection.
* syscall.c (qualify_scno, qualify_syscall_class, qualify_syscall_name):
New functions.
(qual_syscall): Use them.
ioctl_block.c:48: warning: 'init_magic' defined but not used
* tests/ioctl_block.c (init_magic): Define only for
[BLKTRACESETUP && HAVE_STRUCT_BLK_USER_TRACE_SETUP].

This change moves remaining arch specific getregs_old code into
appropriate arch subdirectories and removes unnecessary code
duplication.
* linux/getregs_old.h: New file.
* linux/powerpc/getregs_old.h: Likewise.
* linux/powerpc64/getregs_old.h: Likewise.
* linux/x86_64/getregs_old.h: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* syscall.c: Include "getregs_old.h".
[X86_64 || POWERPC]: Remove.
[ARCH_REGS_FOR_GETREGSET] (ptrace_getregset_or_getregs): Define
to ptrace_getregset.
[ARCH_REGS_FOR_GETREGS] (ptrace_getregset_or_getregs): Define
to ptrace_getregs.
(get_regs): Check for ptrace_getregset_or_getregs instead
of ARCH_REGS_FOR_GETREGSET and ARCH_REGS_FOR_GETREGS. Use
ptrace_getregset_or_getregs instead of ptrace_getregset and
ptrace_getregs. Check for HAVE_GETREGS_OLD instead of X86_64
and POWERPC. Use use_getregs_old instead of getregset_support
and old_kernel.
In order to avoid name clash on distributions which decide to include
kernel headers instead of UAPI ones. For example, on SLES 11SP4:
gcc -DHAVE_CONFIG_H -I./linux/x86_64 -I./linux -I. -Wall -O2 -c net.c
