FROM ISSUE TRACKER ------- Additional Comments From jgarzik 2003-07-08 13:34 ------- Would it be ok to all parties involved, if I made this bug public? I would like Intel to be able to view it as well. And since it's in issue present in upstream, I believe this bug need not be private. ------- Additional Comments From ltroan 2003-07-08 17:46 ------- Event posted 07-08-2003 01:40pm by ltroan Will get a reading from Dell this afternoon about opening this bug up for Public Viewing ------------------- I TALKED WITH DELL AND THEY AGREED TO OPEN THIS BUG UP FOR PUBLIC VIEWING. See also Bugzilla 90320 "e1000_4412k driver stack usage" identified by Dell Engineering with a RHEL2.1 Update3 target. Added to U3 blocker list. Sure looks like a DUP. Jeff, do you agree? If so, suggest closing this BUG as DUP of 107552. *** This bug has been marked as a duplicate of 90320 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
The network drivers are allocating large structures on the kernel stack. When several do this, and they get called in series, it can cause stack overflow. These structs should be allocated via kmalloc/kfree. In the 2.4.9-e.18 kernel: e1000: e1000_check_copper_options() uses 0x1d0 bytes. e1000_ethtool_ioctl() uses 0x2c8 bytes. e1000_check_options() uses 0x15c bytes. ---------- Action by: mdomsch Issue Registered ---------- Action by: mdomsch Status set to: Waiting on Tech ISSUE TRACKER 21176 opened as sev 2.
