2024-03-11Cygwin: getgrent: don't skip SAM-only builtin-accountsCorinna Vinschen1-3/+8
Since commit 15e82eef3a40b ("Cygwin: getgrent: fix local SAM enumeration on domain member machines") we skip enumerating local BUILTIN accounts if we also enumerate AD. However, there are two local accounts which are only available in local SAM, not in AD. Don't skip enumerating those. Fixes: 15e82eef3a40b ("Cygwin: getgrent: fix local SAM enumeration on domain member machines") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2024-02-20Cygwin: getgrent: fix local SAM enumeration on domain member machinesCorinna Vinschen1-3/+9
Don't skip output of local SAM groups on domain member machines. They can have valid, user-defined groups in their SAM. Just skip builtin groups if we're enumerating AD as well. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2022-05-29Cygwin: simplify some function namesKen Brown1-20/+8
Remove "32" or "64" from each of the following names: acl32, aclcheck32, aclfrommode32, aclfrompbits32, aclfromtext32, aclsort32, acltomode32, acltopbits32, acltotext32, facl32, fchown32, fcntl64, fstat64, _fstat64, _fstat64_r, ftruncate64, getgid32, getgrent32, getgrgid32, getgrnam32, getgroups32, getpwuid32, getpwuid_r32, getuid32, getuid32, initgroups32, lseek64, lstat64, mknod32, mmap64, setegid32, seteuid32, setgid32, setgroups32, setregid32, setreuid32, setuid32, stat64, _stat64_r, truncate64. Remove prototypes and macro definitions of these names. Remove "#ifndef __INSIDE_CYGWIN__" from some headers so that the new names will be available when compiling Cygwin. Remove aliases that are no longer needed. Include <unistd.h> in fhandler_clipboard.cc for the declarations of geteuid and getegid.
2022-05-29Cygwin: remove some 32-bit-only function definitionsKen Brown1-98/+0
Remove the definitions of the following: acl, aclcheck, aclfrommode, aclfrompbits, aclfromtext, aclsort, acltomode, acltopbits, acltotext, chown, fchown, _fcntl, fstat, _fstat_r, ftruncate, getegid, geteuid, getgid, getgrent, getgrgid, getgrnam, getgroups, getpwduid, getpwuid, getpwuid_r, getuid, initgroups, lacl, lacl32, lchown, lseek, lstat, mknod, mmap, setegid, seteuid, setgid, setgroups, setregid, setreuid, setuid, stat, _stat_r, truncate. [For most of these, the corresponding 64-bit entry points are obtained by exporting aliases. For example, acl is an alias for acl32, and truncate is an alias for truncate64.] Remove the following structs and all code using them (which is 32-bit only): __stat32, __group16, __flock32, __aclent16_t. Remove the typedefs of __blkcnt32_t __dev16_t, __ino32_t, which are used only in code that has been removed. Put the typedefs of __uid16_t and __gid16_t in one header, instead of one header if __INSIDE_CYGWIN__ is defined and a different header otherwise.
2020-08-05Cygwin: Add 'fallthrough' pseudo keyword for switch/case useCorinna Vinschen1-2/+2
This patch has been inspired by the Linux kernel patch 294f69e662d1 compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case use written by Joe Perches <joe AT perches DOT com> based on an idea from Dan Carpenter <dan DOT carpenter AT oracle DOT com>. The following text is from the original log message: Reserve the pseudo keyword 'fallthrough' for the ability to convert the various case block /* fallthrough */ style comments to appear to be an actual reserved word with the same gcc case block missing fallthrough warning capability. All switch/case blocks now should end in one of: break; fallthrough; goto <label>; return [expression]; continue; In C mode, GCC supports the __fallthrough__ attribute since 7.1, the same time the warning and the comment parsing were introduced. Cygwin-only: add an explicit -Wimplicit-fallthrough=5 to the build flags.

2019-01-24Cygwin: seteuid: work with password-less user switch as wellCorinna Vinschen1-1/+1
The previous patch failed with password-less auth because in that case the return code from get_server_groups wasn't tested. Fix that. Also make sure that get_server_groups does not check if the account is disabled or locked out when just fetching the group list for initgroups or getgrouplist.
