Red Hat Bugzilla – Bug 4651
Bad command line arguments cause a core dump :-(

[mrsam@gwl mrsam]$ rpm -q rpm rpm-3.0.2-6.0 [mrsam@gwl mrsam]$ cat $HOME/.rpmmacros %_topdir /home/mrsam/src/rpm %_pgpbin /usr/local/bin/pgp %_pgp_path /home/mrsam/.pgp %_signature pgp %_pgp_name mrsam@geocities.com [mrsam@gwl mrsam]$ ls $HOME/.pgp config.txt pubring.bak randseed.bin secring.pgp keys.pgp pubring.pgp secring.bak [mrsam@gwl mrsam]$ rpm -ba --sign Segmentation fault (core dumped)
I cannot reproduce this bug without more information. What argument/macro is causing the segfault?
Apparently the core dump occurs because of the -ba flag without any actual spec file given, and both -ba and --sign must be present as well. rpm -ba results in an error message. rpm --sign results in an error message. rpm -ba --sign results in a core dump. Tail end of strace: open("/usr/lib/rpm/i686-linux/macros", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/rpm/macros", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/rpm/i686-linux/macros", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/mrsam/.rpmmacros", O_RDONLY) = 3 fstat(3, {st_mode=032760, st_size=0, ...}) = 0 mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40000000 read(3, "%_topdir\t/home/mrsam/src/rpm\n%"..., 4096) = 104 read(3, "", 4096) = 0 close(3) = 0 munmap(0x40000000, 4096) = 0 --- SIGSEGV (Segmentation fault) --- +++ killed by SIGSEGV +++
Here's why rpm is dumping core: rpm.c, line 1125, function call to poptGetArgs In function poptGetArgs (popt.c line 487): The first if statement evaluates to true, causing the function to return NULL. rpm.c, line 1125, argv gets set to NULL. rpm.c, line 1126: while (*argv) BOOM!!!!!!!
This will be fixed in rpm-3.0.3-0.18. Thanks for the analysis.
