pxe: fix handling of absolute paths

2013-11-04T16:24:22+00:00

pxelinux and syslinux differ in their handling of absolute paths in menu
files. A pxelinux path is aways prepended with the bootfile path while
syslinux allows for absolute paths. u-boot was always treating a leading
/ as an absolute path breaking some pxelinux setups. Fix this by adding
a flag to distinguish pxelinux vs. syslinux behavior.

Prevent null pointer dereference originating in cmd_pxe.c

2013-10-14T20:49:20+00:00

Pass a valid cmdtp into do_tftpb(), do_ext2load(), and do_get_fat(), to
avoid possible crashes due to null pointer dereferencing.

Commit d7884e047d08447dfd1374e9fa2fdf7ab36e56f5 does not go far enough.
There is still at least one call chain that can result in a crash.

The do_tftpb(), do_ext2load(), and do_get_fat() functions expect a valid
cmdtp.  Passing in NULL is particularly bad in the do_tftpb() case,
because eventually boot_get_kernel() will be called with a NULL cmdtp:

do_tftpb() -> netboot_common() -> bootm_maybe_autostart() -> do_bootm()
-> do_bootm_states() -> bootm_find_os() -> boot_get_kernel()

Around line 991 in cmd_bootm.c, boot_get_kernel() will dereference the
null pointer, and the board will crash.

cmd_pxe.c: Pass along 'cmdtp' to do_bootm()/do_bootz()

2013-09-24T13:05:08+00:00

When we call do_bootm() with a vmlinuz, this would lead to a NULL
pointer dereference, and after talking with Wolfgang the right thing to
do here for now is to make sure that we pass cmdtp to these functions
rather than NULL.

net: Fix build regression in cmd_pxe.c

Not all boards define an SOC.  As a result, we can't depend on that.

pxe: add support for per arch and SoC default paths

2013-06-25T00:07:34+00:00

A pxelinux server setup for "default" menu is typically an x86 binary.
This does not work well with a mixed architecture setup. Extend the default
search to look for default-- and then default- before
falling back to just "default".

pxe: add support for ontimeout token

2013-06-25T00:07:34+00:00

ontimeout is similar to default, but is the selection on menu timeout.
This is how cobbler sets a default. The label default is supposed to be
the default selection when  is pressed. If both default and
ontimeout are set, last one parsed wins.

pxe: simplify menu display and selection

2013-06-25T00:07:34+00:00

Menus with lots of entries and long append lines are hard to read.
Just show a numbered list using the label or name and make the choice
by entering the number.
