lock -n is similiar to flock -n. If the lock was already taken,
fail with exit code = 1 and write error message to stderr.
example:
if ! lock -n /tmp/foo ; then
echo lock exits.
else
echo lock was free. But is locked now.
fi
> lock was free. But is locked now.
> lock exists.

This enables passworldless login for root via SSH whenever no root
password is set (e.g. after reset, flashing without keeping config
or in failsafe) and removes telnet support alltogether.

This controls the old Broadcom switch driver which was removed over a
year ago, since then this is useless. Use swconfig instead it works
with more (Broadcom) switches.

This reverts commit r45579.
With the latest change r46251 ("nvram: fix "Segmentation fault" caused
by setting memory out of buffer") nvram utility shouldn't crash anymore.
It was tested on 3 brcm47xx devices:
1) Unknown with 0x10000 NVRAM size (0x8000 offset)
2) Linksys E1000 V2.1 with 0x10000 (0x8000 offset)
3) Linksys WRT300N V1 with 0x10000 (0x8000 offset)
And 3 bcm53xx devices:
1) Buffalo WZR-600DHP2 with 0x160000 NVRAM size
2) Buffalo WZR-1750DHP with 0x10000 NVRAM size
3) Netgear R6250 V1 with 0x180000 NVRAM size
(all using 0 offset)
This is an important change as it allows reading whole NVRAM. This may
critical when reading some basic configuration (e.g. switch ports).

Some MTD partitions with NVRAM have content starting in the middle. In
such case offset is set and nvram_header returns pointer to the middle.
It means we have to respect offset when calculating remaining space.
By the way use real MTD partition size (nvram_part_size variable) as we
may want to bump NVRAM_SPACE in the (very near) future.

Without this the condition

So far we got only one generic function accessing this table, but
implementing optimizations will require calculating crc32 in other code
parts as well.

This reverts commit ff84c27a281bc19df19bc62ee8688cca5586f6e3.
This tool has really broken size handling (many values hardcoded), it
crashes right now in case of NVRAM not filling whole MTD partition.

For years Broadcom devices use 64 KiB NVRAM partition size and some of
them indeed have it filled in more than 50%. This change allows handling
whole NVRAM e.g. on Netgear WNDR4500 and Netgear R8000.
The same fix was applied to kernel in upstream commit 6ab7c29.

We don't have broadcom-diag for months or years now and the correct
solution is to simply don't have "nvram" partition on WGT634U anyway.
