* Fix most of clang -Wcast-align compilation warningsDmitry V. Levin2020-03-191-2/+5
| | | | | | | | | | | | | | | | | | | Unlike gcc, clang is not smart enough to infer the alignment of structure fields, so add some alignment hints to the code. * libpam/include/pam_cc_compat.h (PAM_ATTRIBUTE_ALIGNED): New macro. * modules/pam_namespace/md5.h: Include "pam_cc_compat.h". (struct MD5Context): Add PAM_ATTRIBUTE_ALIGNED to "in" field. * modules/pam_namespace/md5.c [!(__i386__ || __x86_64__)] (uint8_aligned): New type. [!(__i386__ || __x86_64__)] (byteReverse): Use it instead of unsigned char. * modules/pam_timestamp/sha1.h: Include "pam_cc_compat.h". (struct sha1_context): Add PAM_ATTRIBUTE_ALIGNED to pending field. * modules/pam_unix/md5.h: Include "pam_cc_compat.h". (struct MD5Context): Add PAM_ATTRIBUTE_ALIGNED to "in" field. * modules/pam_unix/md5.c [!HIGHFIRST] (uint8_aligned): New type. [!HIGHFIRST] (byteReverse): Use it instead of unsigned char.
* Fix strict aliasing issue in MD5 implementations.Tomas Mraz2013-03-281-2/+1

* Fix whitespace issuesDmitry V. Levin2011-10-261-1/+1
| | | | | | Cleanup trailing whitespaces, indentation that uses spaces before tabs, and blank lines at EOF. Make the project free of warnings reported by git diff --check 4b825dc642cb6eb9a060e54bf8d69288fbee4904 HEAD
