Are you seeing this on any other BSP? 31128 2 corneliux.stoicescu 2013-03-25 15:55:01 +0000 It is a general issue with core-image-minimal images. I believe I should have placed this in the OE-CORE product. Changing accordingly. 31161 3 Qi.Chen 2013-03-26 08:14:31 +0000 confirmed on qemux86 and qemuarm. And it's not restricted to minimal image. The same problem appeared on sato-sdk image: root@qemuarm:/etc# login qemuarm login: jfiewoefiwof Password: Segmentation fault 31162 4 corneliux.stoicescu 2013-03-26 08:25:07 +0000 Indeed but it is not a general issue. core-image-lsb-sdk for instance does not have this issue (tested core-image-lsb-sdk-jasperforest). 31587 5 sgw 2013-04-05 02:33:16 +0000 I debugged this issue down to the new version of the crypt() code in eglibc 2.17, it expects 2 valid chars as part the chipher, or it returns NULL. The tinylogin code uses the return to do a strcmp(). This causes the segfault. There is also an issue in the shadow version of login, but manifests itself as a perror: crypt: Invalid Argument. There are potential fixes for both of these that are being looked into currently. 31699 6 sgw 2013-04-08 15:01:23 +0000 http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=59c073514c01b018f6123bb177141888b6f8c8ee 32809 7 alexandrux.palalau 2013-05-01 13:24:18 +0000 Verified on master branch: Commit ID: c42cc8fb38aee46f4778b9c68412a47ae5919923
