2007-04-17fix bogon in /dev/mem mmap'ing on nommuBenjamin Herrenschmidt
While digging through my MAP_FIXED changes, I found that rather obvious bug in /dev/mem mmap implementation for nommu archs. get_unmapped_area() is expected to return an address, not a pfn.

Commit d720bc4b8fc5d6d179ef094908d4fbb5e436ffad partially removed a private implementation of baud speed decoding. However it doesn't seem to be complete: after the speed is decoded, it is still being used as an index to a local speed table (array overrun, no doubt).

2007-03-18[PATCH] tty: Fix two reported pid leaksEric W. Biederman
These leaks were reported by: Catalin Marinas <catalin.marians@gmail.com> and I have been able to very by inspection they are possible. When converting tty_io.c to store pids as struct pid pointers instead of pid_t values it appears I overlooked two places where we stop using the pid value. The very obvious one is in do_tty_hangup, and the one the less obvious one in __proc_set_tty. When looking into the code __proc_set_tty only has pids that need to be put because of failures of other parts of the code to properly perform hangup processing. Fixing the leak here in __proc_set_tty is easy and obviously correct so I am doing that first. Fixing the places that should be performing hangup processing is much less obviously correct. So those I'm aiming those patches at -mm. for now, so the can age a while before they are merged. Signed-off-by: Eric W.

2007-03-01[PATCH] tty_io: fix race in master pty close/slave pty close pathAristeu Sergio Rozanski Filho
This patch fixes a possible race that leads to double freeing an idr index. When the master begin to close, release_dev() is called and then pty_close() is called: if (tty->driver->close) tty->driver->close(tty, filp); This is done without helding any locks other than BKL. Inside pty_close(), being a master close, the devpts entry will be removed: #ifdef CONFIG_UNIX98_PTYS if (tty->driver == ptm_driver) devpts_pty_kill(tty->index); #endif But devpts_pty_kill() will call get_node() that may sleep while waiting for &devpts_root->d_inode->i_sem. When this happens and the slave is being opened, tty_open() just found the driver and index: driver = get_tty_driver(device, &index); if (!driver) { mutex_unlock(&tty_mutex); return -ENODEV; } This part of the code is already protected under tty_mute. The problem is that the slave close already got an index. Then init_dev() is called and blocks waiting for the same &devpts_root->d_inode->i_sem. When the master close resumes, it removes the devpts entry, and the relation between idr index and the tty is gone. The master then sleeps waiting for the tty_mutex on release_dev(). Slave open resumes and found no tty for that index. As result, a NULL tty is returned and init_dev() doesn't flow to fast_track: /* check whether we're reopening an existing tty */ if (driver->flags & TTY_DRIVER_DEVPTS_MEM) { tty = devpts_get_tty(idx); if (tty && driver->subtype == PTY_TYPE_MASTER) tty = tty->link; } else { tty = driver->ttys[idx]; } if (tty) goto fast_track; The result of this, is that a new tty will be created and init_dev() returns sucessfull. After returning, tty_mutex is dropped and master close may resume. Master close finds it's the only use and both sides are closing, then releases the tty and the index. At this point, the idr index is free, but slave still has it. Slave open then calls pty_open() and finds that tty->link->count is 0, because there's no master and returns error. Then tty_open() calls release_dev() which executes without any warning, as it was a case of last slave close when the master is already closed (master->count == 0, slave->count == 1). The tty is then released with the already released idr index. This normally would only issue a warning on idr_remove() but in case of a customer's critical application, it's never too simple: thread1: opens master, gets index X thread1: begin closing master thread2: begin opening slave with index X thread1: finishes closing master, index X released thread3: opens master, gets index X, just released thread2: fails opening slave, releases index X <---- thread4: opens master, gets index X, init_dev() then find an already in use and healthy tty and fails If no more indexes are released, ptmx_open() will keep failing, as the first free index available is X, and it will make init_dev() fail because you're trying to "reopen a master" which isn't valid. The patch notices when this race happens and make init_dev() fail imediately. The init_dev() function is called with tty_mutex held, so it's safe to continue with tty till the end of function because release_dev() won't make any further changes without grabbing the tty_mutex. Without the patch, on some machines it's possible get easily idr warnings like this one: idr_remove called for id=15 which is not allocated.

2007-02-17rio: typo in bitwise AND expression.Willy Tarreau
The line : hp->Mode &= !RIO_PCI_INT_ENABLE; is obviously wrong as RIO_PCI_INT_ENABLE=0x04 and is used as a bitmask 2 lines before. Getting no IRQ would not disable RIO_PCI_INT_ENABLE but rather RIO_PCI_BOOT_FROM_RAM which equals 0x01. Obvious fix is to change ! for ~.

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2007-02-14[PATCH] sysctl: remove sys_sysctl support from drivers/char/rtc.cEric W. Biederman
The real time clock driver was using the binary number reserved for cdroms in the sysctl binary number interface, which is a no-no. So since the sysctl binary interface is wrong remove it.
