From 805b789a69b664bbcf9a93bff85b90d1c60bfbf5 Mon Sep 17 00:00:00 2001 From: Andrzej Hunt Date: Sun, 25 Apr 2021 14:16:18 +0000 Subject: [PATCH] builtin/rebase: release git_format_patch_opt too options.git_format_patch_opt can be populated during cmd_rebase's setup, and will therefore leak on return. Although we could just UNLEAK all of options, we choose to strbuf_release() the individual member, which matches the existing pattern (where we're freeing invidual members of options). Leak found when running t0021: Direct leak of 24 byte(s) in 1 object(s) allocated from: #0 0x49ab79 in realloc ../projects/compiler-rt/lib/asan/asan_malloc_linux.cpp:164:3 #1 0x9ac296 in xrealloc wrapper.c:126:8 #2 0x93b13d in strbuf_grow strbuf.c:98:2 #3 0x93bd3a in strbuf_add strbuf.c:295:2 #4 0x60ae92 in strbuf_addstr strbuf.h:304:2 #5 0x605f17 in cmd_rebase builtin/rebase.c:1759:3 #6 0x4cd91d in run_builtin git.c:467:11 #7 0x4cb5f3 in handle_builtin git.c:719:3 #8 0x4ccf47 in run_argv git.c:808:4 #9 0x4caf49 in cmd_main git.c:939:19 #10 0x69dbfe in main common-main.c:52:11 #11 0x7f66dae91349 in __libc_start_main (/lib64/libc.so.6+0x24349) SUMMARY: AddressSanitizer: 24 byte(s) leaked in 1 allocation(s).
