Enhance abbrev=, raw=, and verbose= to accept the same syntax as trace=.
For example, this allows such syntax as -e verbose=file.
* syscall.c (lookup_class): Define before qual_syscall.
(qualify): Move the loop based on lookup_class ...
(qual_syscall): ... here.
* tests/qual_syscall.test: Check it.
fadvise_64_64 decoder used before this change prints different sign
of the "len" argument (loff_t vs size_t).
* linux/x32/syscallent.h (fadvise64): Replace SEN(fadvise64_64)
with SEN(fadvise64).
Since its type is size_t, it is 64-bit wide on x32 and special care
should be taken in order to obtain it.
* fadvise.c (SYS_FUNC(fadvise64)): Use getarg_ull for obtaining value
of "len" syscall argument.
These allow retrieving specific argument in full taking into account
peculiarities of runtimes which employ tcp->ext_arg (e.g. x32).
* defs.h (getarg_ll, getarg_ull): New prototypes.
* util.c (getarg_ll, getarg_ull): New functions.
(printargs): Use getarg_ull.
The kernel declares fadvise64 as
long sys_fadvise64(int fd, loff_t offset, size_t len, int advice);
* fadvise.c (SYS_FUNC(fadvise64)): Change conversion specifier from
"%ld" to "%lu" for printing len argument since kernel expects argument
of type size_t.
This change is no-op yet, but things will change when decoder
of fadvise64 syscall get fixed.
* linux/sh64/syscallent.h (fadvise64_64): Replace SEN(fadvise64)
with SEN(fadvise64_64).
* linux/sparc64/syscallent.h (fadvise64_64): Likewise.
Since types of these arguments are off_t and kernel actually expects
signed values in order to fail when negative values are provided,
lets display these values as signed.
* fallocate.c (SYS_FUNC(fallocate)): Change conversion specifier for
printing "offset" and "len" syscall arguments from %llu to %lld.
Support for these quota subcommands by linux kernels has been dropped
long time ago (between 2.5.16 and 2.5.17), so lets drop it in order
to minimize amount of code which should be subjected to testing and
structured conversion.
* quota.c (struct v1_dqblk, struct v2_dqblk, struct v2_dqinfo,
struct v1_dqstats, struct v2_dqstats): Remove.
(decode_cmd_data): Remove handling of Q_V1_GETQUOTA, Q_V1_SETQUOTA,
Q_V2_GETQUOTA, Q_V2_SETQUOTA, Q_V2_GETINFO, Q_V2_SETINFO, Q_V1_GETSTATS,
and Q_V2_GETSTATS subcommands.
(SYS_FUNC(quotactl)): Remove handling of Q_V1_QUOTAON subcommand.
Since the only difference between 32-bit and 64-bit environments
regarding this structure is its padding, lets just add packed attribute
to its definition instead of going full mpers.
* quota.c (struct if_dqblk): Add ATTRIBUTE_PACKED.
Q_XQUOTASYNC is no-op, but it does not require id/addr arguments anyway.
* quota.c (decode_cmd_data): Add Q_SYNC and Q_XQUOTASYNC to subcommand
dispatch switch since id/addr arguments for these subcommands are known
to be ignored.
As id argument is not used for Q_QUOTAOFF, Q_GETFMT, Q_V2_GETINFO,
Q_GETINFO, Q_V2_SEETINFO, Q_SETINFO, Q_SYNC, Q_XQUOTAON, Q_XQUOTAOFF,
Q_XQUOTARM, Q_XGETQSTAT, Q_XGETQSTATV, Q_XQUOTASYNC, Q_V1_GETSTATS, and
Q_V2_GETSTATS subcommands, do not print it for these subcommands.
* quota.c (decode_cmd_data): Add id argument parameter, add printing
of id argument for Q_GETQUOTA, Q_SETQUOTA, Q_GETNEXTQUOTA,
Q_V1_GETQUOTA, Q_V1_SETQUOTA, Q_V2_GETQUOTA, Q_V2_SETQUOTA,
Q_XGETQUOTA, Q_XGETNEXTQUOTA, Q_XSETQLIM, and unknown subcommands.
(SYS_FUNC(quotactl)): Remove printing of id argument, pass it
to decode_cmd_data.
* quota.c (SYS_FUNC(quotactl)): Since id call argument is used for
user/group/project ID which all have special semantics for -1,
print it the same way as UIDs are printed.
Introduce VERBOSE macro (defaults to 0) that is expected to be defined
to 1 by code testing "strace -v" output.
* tests/tests.h [!VERBOSE] (VERBOSE): New macro.
O_TMPFILE reqires the mode argument (just like O_CREAT), so print it.
* open.c (STRACE_O_TMPFILE): New macro.
(decode_open): Print the mode argument when O_TMPFILE flag is set.
* tests/open.c (main): Check it.
Fixes RH#1377846.
