The first argument of match_diff should be the file with expected
output, the second argument - the file with actual output.
* tests/aio.test: Swap match_diff arguments.
* tests/restart_syscall.test: Likewise.
* tests/seccomp.test: Likewise.
* tests/umovestr2.test: Likewise.
Introduce a new helper function to fetch tracee's long integers
and use it to fix multiple personalities support in io_submit parser.
* defs.h (umove_long_or_printaddr): New prototype.
* util.c (umove_long_or_printaddr): New function.
* aio.c (sys_io_submit): Use it to fetch tracee's pointers.
* tests/aio.c: New file.
* tests/aio.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add aio.
(TESTS): Add aio.test.
* tests/.gitignore: Add aio.
Currently the code assumes the set of valid options between getsockopt
and setsockopt are exactly the same and thus maintains one list. The
kernel unfortunately does not do this -- it allows for different opts
between the get and set functions. See the {g,s}et_opt{min,max} fields
in the various netfilter subcores.
To support this, extend the printxval function to take multiple sets of
xlats as varargs. Then we add the new get/set lists, and pass them down
in the net code when decoding things.
A simple example is iptables; before:
getsockopt(4, SOL_IP, 0x40 /* IP_??? */, ...) = 0
getsockopt(4, SOL_IP, 0x41 /* IP_??? */, ...) = 0
after:
getsockopt(4, SOL_IP, IPT_SO_GET_INFO, ...) = 0
getsockopt(4, SOL_IP, IPT_SO_GET_ENTRIES, ...) = 0
If these were setsockopt calls, then 0x40 & 0x41 would be
IPT_SO_SET_REPLACE & IPT_SO_SET_ADD_COUNTERS.
* configure.ac: Check for netfilter headers.
* defs.h (printxvals): New prototype.
(printxval): Change to a define.
* net.c: Include netfilter headers and new sockopts headers.
(print_sockopt_fd_level_name): Add a is_getsockopt argument. Change SOL_IP
and SOL_IPV6 decoding to use printxvals, and use is_getsockopt to pass more
xlats down.
(getsockopt): Call print_sockopt_fd_level_name with is_getsockopt as true.
(setsockopt): Call print_sockopt_fd_level_name with is_getsockopt as false.
* util.c (printxval): Rename to ...
(printxvals): ... this. Rewrite to be varargs based.
* xlat/getsockipoptions.in: New xlat list.
* xlat/getsockipv6options.in, xlat/setsockipoptions.in,
xlat/setsockipv6options.in: Likewise.
When msgrcv syscall is an ipc subcall, msgp (pointer to struct msgbuf)
and msgtyp (message type) syscall arguments are passed via proxy
structure which definition significantly depends on tracee's
wordsize.
* ipc_msg.c (fetch_msgrcv_args): New function.
(sys_msgrcv): Use it.
* tests/sendfile.c: New file.
* tests/sendfile64.c: New file.
* tests/sendfile.test: New test.
* tests/sendfile64.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add sendfile and sendfile64.
(TESTS): Add sendfile.test and sendfile64.test.
* tests/.gitignore: Add sendfile and sendfile64.
When sendfile is called with a valid pointer to a file offset variable,
kernel updates this variable on successfull exit from syscall.
* sendfile.c (sys_sendfile, sys_sendfile64): Print tcp->u_arg[2]
on exiting syscall as well as on entering.
When receiving SIGSYS, the si_syscall & si_arch fields are set to known
values, so make sure we decode their values into the symbol settings.
This makes stracing seccomp failures much easier.
* defs.h (syscall_name): New prototype.
* printsiginfo.c: Include linux/audit.h and xlat/audit_arch.h.
(print_si_info): Decode si_syscall & si_arch for SIGSYS.
* syscall.c (undefined_scno_name): Delete.
(syscall_name): New function.
(trace_syscall_entering): Change undefined_scno_name to syscall_name.
(trace_syscall_exiting): Likewise.
* xlat/audit_arch.in: New file.
struct sysinfo members totalhigh, freehigh and mem_unit are present
since Linux 2.3.48.
* configure.ac (AC_CHECK_MEMBERS): Remove struct sysinfo checks.
* sysinfo.c (sys_sysinfo): Remove HAVE_STRUCT_SYSINFO_* checks.
* net.c (sys_socket): Set RVAL_FD flag in the return code.
* tests/net-yy-accept.awk: Update socket and bind regexps.
* tests/unix-yy-accept.awk: Likewise.
* tests/net-yy-connect.awk: Update socket and connect regexps.
* tests/unix-yy-connect.awk: Likewise.
