| 2015-12-17 | Add copyright headers to some files which lack them | Dmitry V. Levin | |
| Before this change, all files that exist since 20th century had copyright headers, while most files that appeared later didn't. This change fixes the inconsistency by adding missing copyright headers. It doesn't mean that copyright headers became maintained. In my view, git history provides much better information on this subject and is much more accurate than copyright headers. | |||
| 2015-07-20 | capability.c: make use of RVAL_DECODED | Dmitry V. Levin | |
| * capability.c (sys_capset): Update for RVAL_DECODED. | |||
| 2015-07-20 | capability.c: use printaddr and umove_or_printaddr | Dmitry V. Levin | |
| * capability.c (get_cap_header): Use printaddr. (print_cap_data): Use printaddr and umove_or_printaddr. | |||
| 2015-04-07 | Declare syscall parsers using SYS_FUNC macro | Dmitry V. Levin | |
| Introduce SYS_FUNC macro to declare and define all syscall parsers. * Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h. (sys_func.h): New rule. * defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros. * linux/syscall.h: Include "sys_func.h". [NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers. Remove other declarations. * linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs and osf_fstatfs syscall parsers. * *.c: Use SYS_FUNC to define syscall parsers. | |||
| 2015-03-21 | Change last parameter of umoven() from char* to void* | Denys Vlasenko | |
| Saves tons of casts. Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com> | |||
| 2015-02-19 | Move CAP_* definitions out to header files | Dmitry V. Levin | |
| * Makefile.am (strace_SOURCES): Add caps0.h and caps1.h. * caps0.h: New file. * caps1.h: New file. * capability.c: Remove CAP_* definitions, include "caps0.h" and "caps1.h" instead. Include "xlat/cap_mask0.h" instead of "xlat/capabilities.h". Include "xlat/cap_mask1.h" instead of "xlat/capabilities1.h". (print_cap_bits): Update callers. * xlat/capabilities.in: Rename to xlat/cap_mask0.in. * xlat/capabilities1.in: Rename to xlat/cap_mask1.in. | |||
| 2014-12-06 | Implement full decoding of 64-bit capabilities | Dmitry V. Levin | |
| Unlike v1 capabilities which are 32-bit, v2 and v3 are 64-bit, but before this change only lower 32 capability bits were decoded for v2 and v3. * xlat/capabilities1.in: New file. * capability.c: Define v2/v3 CAP_* constants. Include xlat/capabilities1.h. (get_cap_header): New function. (print_cap_header): Update to use get_cap_header result. (print_cap_data): Decoder higher capability bits for v2 and v3. (sys_capget, sys_capset): Use get_cap_header, update print_cap_header and print_cap_data calls. * tests/caps.c: New file. * tests/caps.awk: New file. * tests/caps.test: New test. * tests/Makefile.am (CHECK_PROGRAMS): Add caps. (TESTS): Add caps.test. (EXTRA_DIST): Add caps.awk. | |||
| 2014-12-06 | Make parsers of capget and capset syscalls self-contained | Dmitry V. Levin | |
| Various versions of <linux/capability.h> used to require different workarounds to avoid conflicts with types defined by libc headers. Define all required types and constants locally to fix this issue. * configure.ac (AC_CHECK_HEADERS): Remove linux/capability.h. * capability.c: Do not include <linux/capability.h>, remove workarounds for problematic versions of <linux/capability.h> file. Define CAP_* and _LINUX_CAPABILITY_VERSION_* constants as enums. (struct __user_cap_header_struct, struct __user_cap_data_struct): Define. * xlat/cap_version.in: Add #unconditional. * xlat/capabilities.in: Likewise. | |||
| 2014-12-04 | Move capget and capset parsers to a separate file | Dmitry V. Levin | |
| * capability.c: New file. * Makefile.am (strace_SOURCES): Add it. * system.c: Move inclusion of headers and macro definitions related to capget and capset decoding to capability.c. (print_cap_header, print_cap_data, sys_capget, sys_capset): Move to capability.c. | |||
