Created attachment 1122783 [details] Test program Description of problem: When glfs_lseek() API is used with SEEK_SET and SEEK_CUR to reposition the open file associated with a fd to the specified offset, even though the operation is success it is not returning the resulting offset location and instead -1 is returned. Version-Release number of selected component (if applicable): mainline How reproducible: always Steps to Reproduce: 1. Compile and build glusterfs under /usr/local/. 2. Create and start a simple distribute volume. 3. Download the attached test program and compile it. # gcc gfapi-test-lseek.c -lgfapi -I /usr/local/include/glusterfs/ -L /usr/local/lib/ 4. Export LD_LIBRARY_PATH # export LD_LIBRARY_PATH=/usr/local/lib 5. Run a.out # ./a.out <volume-name> <server ip/hostname> Actual results: Program produced the following error message: glfs_lseek with SEEK_SET returned -1, but expected 5 glfs_lseek with SEEK_CUR returned -1, but expected 10 Expected results: Program should run successfully with out displaying any error message.

COMMIT: http://review.gluster.org/13423 committed in master by Niels de Vos (ndevos) ------ commit 095e2c48271a5248c8711a4e6a34bcb4d44c440e Author: Anoop C S <anoopcs> Date: Wed Feb 10 17:08:26 2016 +0530 api: glfs_lseek must return repositioned offset for SEEK_SET, SEEK_CUR flags On success, glfs_lseek() API is responsible for providing the repositioned offset as its return value. But for SEEK_SET and SEEK_CUR flags, glfs_lseek() returns -1 on successfully repositioning the fd offset. Current change is to set ret to 0 after glfd->offset is modified correctly so as to return the correct offset.
