sandbox: Fix warnings in hashtable.c

2011-11-22T07:40:05+00:00

This fixes a few printf() strings for size_t which are missing the 'z'
modifier.

env: allow to export only selected variables

2011-11-08T12:20:42+00:00

New syntax:
	env export [-t | -b | -c] [-s size] addr [var ...]

With this change it is possible to provide a list of variables names
that shall be exported.  Whenno arguments are given, the whole
environment gets exported.

NOTE: The new handling of the "size" argument means a change to the
user API.

Constify getenv(), setenv() and hash code functions

2011-07-29T23:37:44+00:00

This is needed to get rid of build warnings like

main.c:311: warning: passing argument 2 of 'setenv' discards qualifiers from pointer target type

which result from commit 09c2e90 "unify version_string".

common: add a grepenv command

2011-04-27T23:00:07+00:00

u-boot environments, esp. when boards are shared across multiple
users, can get pretty large and time consuming to visually parse.
The grepenv command this patch adds can be used in lieu of printenv
to facilitate searching.  grepenv works like printenv but limits
its output only to environment strings (variable name and value
pairs) that match the user specified substring.

the following examples are on a board with a 5313 byte environment
that spans multiple screen pages:

Example 1:  summarize ethernet configuration:

=> grepenv eth TSEC
etact=FM1@DTSEC2
eth=FM1@DTSEC4
ethact=FM1@DTSEC2
eth1addr=00:E0:0C:00:8b:01
eth2addr=00:E0:0C:00:8b:02
eth3addr=00:E0:0C:00:8b:03
eth4addr=00:E0:0C:00:8b:04
eth5addr=00:E0:0C:00:8b:05
eth6addr=00:E0:0C:00:8b:06
eth7addr=00:E0:0C:00:8b:07
eth8addr=00:E0:0C:00:8b:08
eth9addr=00:E0:0C:00:8b:09
ethaddr=00:E0:0C:00:8b:00
netdev=eth0
uprcw=setenv ethact $eth;setenv filename p4080ds/R_PPSXX_0xe/rcw_0xe_2sgmii_rev2_high.bin;setenv start 0xe8000000;protect off all;run upimage;protect on all
upuboot=setenv ethact $eth;setenv filename u-boot.bin;setenv start eff80000;protect off all;run upimage;protect on all
upucode=setenv ethact $eth;setenv filename fsl_fman_ucode_P4080_101_6.bin;setenv start 0xef000000;protect off all;run upimage;protect on all
usdboot=setenv ethact $eth;tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/initramfs.cpio.gz.uboot;tftp c00000 $dir/p4080ds-usdpaa.dtb;setenv bootargs root=/dev/ram rw console=ttyS0,115200 $othbootargs;bootm 1000000 2000000 c00000;
=>

Example 2: detect unused env vars:

=> grepenv etact
etact=FM1@DTSEC2
=>

Example 3: reveal hardcoded variables; e.g., for fdtaddr:

=> grepenv fdtaddr
fdtaddr=c00000
nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr
ramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr
=> grep $fdtaddr
fdtaddr=c00000
my_boot=bootm 0x40000000 0x41000000 0x00c00000
my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb
nohvboot=tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/$ramdiskfile;tftp c00000 $dir/$fdtfile;setenv bootargs root=/dev/ram rw ramdisk_size=0x10000000 console=ttyS0,115200;bootm 1000000 2000000 c00000;
=>

This patch also enables the grepenv command by default on
corenet_ds based boards (and repositions the DHCP command
entry to keep the list sorted).

env: fix env var autocompletion

2011-04-27T22:54:40+00:00

commit 560d424b6d7cd4205b062ad95f1b104bd4f8bcc3 "env: re-add
support for auto-completion" fell short of its description -
the 'used' logic in hmatch_r was reversed - 'used' is 0 if
the hash table entry is not used, or -1 if deleted.  This
patch makes hmatch_r actually match on valid ('used') entries,
instead of skipping them and failing to match anything.

typing 'printenv tft' and hitting 'tab' now displays valid
choices for variable names.

Fix hash table deletion to prevent lost entries

2011-03-22T21:43:04+00:00

Use negative used value to mark deleted entry.  Search keeps probing
past deleted entries.  Adding an entry uses first deleted entry when
it hits end of probe chain.

Initially found that "ramdiskimage" and "preboot" collide modulus 347,
causing "preboot" to be inserted at idx 190, "ramdiskimage" at idx 191.
Previous to this fix when "preboot" is deleted, "ramdiskimage" is
orphaned.

hashtable: drop all non-reentrant versions

2010-12-17T20:07:14+00:00

The non-reentrant versions of the hashtable functions operate on a single
shared hashtable.  So if two different people try using these funcs for
two different purposes, they'll cause problems for the other.

Avoid this by converting all existing hashtable consumers over to the
reentrant versions and then punting the non-reentrant ones.
