[PATCH] uml - Fix x86_64 page leak

2005-10-03T23:27:18Z

We were leaking pmd pages when 3_LEVEL_PGTABLES was enabled. This fixes that, has been well tested and is included in mainline tree. Please include in -stable as well. Signed-off-by: Jeff Dike Signed-off-by: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Chris Wright

[PATCH] mmaper_kern.c fixes [buffer overruns]

2005-08-27T17:11:40Z

- copy_from_user() can fail; ->write() must check its return value. - severe buffer overruns both in ->read() and ->write() - lseek to the end (i.e. to mmapper_size) and if (count + *ppos > mmapper_size) count = count + *ppos - mmapper_size; will do absolutely nothing. Then it will call copy_to_user(buf,&v_buf[*ppos],count); with obvious results (similar for ->write()). Fixed by turning read to simple_read_from_buffer() and by doing normal limiting of count in ->write(). - gratitious lock_kernel() in ->mmap() - it's useless there. - lots of gratuitous includes.

[PATCH] uml: fix a crash under screen

Running UML inside a detached screen delivers SIGWINCH when UML is not expecting it. This patch ignores them. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: fix vsyscall brokenness

2005-07-29T22:01:14Z

The #if/#ifdef cleanup exposed a bug in UML's ELF header processing. With this bug fixed, UML recognizes the vsyscall info coming from the host. On FC4, there is a vsyscall page low in the address space, which UML doesn't provide. This causes an infinite page fault loop and a hang on boot. This patch works around that by making this look like a no-vsyscall system. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: Fix load average >=1

2005-07-29T04:46:04Z

update_process_times was missing its irq_enter/irq_exit wrapper. This caused ksoftirqd to be scheduled on every clock tick. Signed-off-by: Jeff Dike Cc: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: Fix redundant assignment

By this point, .is_user has already been set, so this assignment is useless. Signed-off-by: Jeff Dike Cc: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
