* env: Allow returning errors from hdelete_r()Simon Glass2020-12-041-6/+6
| | | | | | | | | | | | | | | | | | | | At present this function returns 1 on success and 0 on failure. But in the latter case it provides no indication of what went wrong. If an attempt is made to delete a non-existent variable, the caller may want to ignore this error. This happens when setting a non-existent variable to "", for example. Update the function to return 0 on success and a useful error code on failure. Add a function comment too. Make sure that env_set() does not return an error if it is deleting a variable that doesn't exist. We could update env_set() to return useful error numbers also, but that is beyond the scope of this change. Signed-off-by: Simon Glass <sjg@chromium.org> wip

| | | | | | | | | | | This option marks any U-Boot variable which does not have explicit 'w' writeable flag set as read-only. This way the environment can be locked down and only variables explicitly configured to be writeable can ever be changed by either 'env import', 'env set' or loading user environment from environment storage.

* command: Remove the cmd_tbl_t typedefSimon Glass2020-05-181-1/+1
| | | | | | | | | | | | | We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
* make env_entry::callback conditional on !CONFIG_SPL_BUILDRasmus Villemoes2020-04-241-1/+0
| | | | | | | | | | | | | | | | | | The callback member of struct env_entry is always NULL for an SPL build. Removing it thus saves a bit of run-time memory in the SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded in struct env_entry_node - i.e. about 2KB for the normal case of 512+change hash table entries. Two small fixups are needed for this, all other references to the callback member are already under !CONFIG_SPL_BUILD: Don't initialize .callback in set_flags() - hsearch_r doesn't use that value anyway. And make env_callback_init() initialize ->callback to NULL for a new entry instead of relying on an unused or deleted entry having NULL in ->callback.

* env: Drop the ACTION typedefSimon Glass2019-08-111-9/+9
| | | | | | | | | | | | Avoid using a typedef here which is unnecessary. Add an 'env_' prefix to both the enum and its members to make it clear that these are related to the environment. Add an ENV prefix to these two flags so that it is clear what they relate to. Also move them to env.h since they are part of the public API. Use an enum rather than a #define to tie them together.

* hashtable: fix environment variable corruptionRoman Kapl2019-02-091-3/+10
| | | | | | | | | | | | | | | | | | | | | | Only first previously deleted entry was recognized, leading hsearch_r to think that there was no previously deleted entry. It then conluded that a free entry was found, even if there were no free entries and it overwrote a random entry. This patch makes sure all deleted or free entries are always found and also introduces constants for the 0 and -1 numbers. Unit tests to excersise a simple hash table usage and catch the corruption were added.

* hashtable: do not recreate whole hash table if vars are passed to himport_rQuentin Schulz2018-07-201-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When vars are passed to the himport_r function with H_NOCLEAR flag, those vars will be overridden in the current environment and if one of those vars is not in the imported environment, it'll be deleted in the current environment whatever the flag passed to himport_r. The H_NOCLEAR flag is used to clear the whole environment whether vars are passed to the function or not. This leads to incoherent behaviour. If one passes vars to himport_r with the H_NOCLEAR flag, if a var in vars is not in the imported env, that var will be removed from the current env. If one passes vars to himport_r without the H_NOCLEAR flag, the whole environment will be removed and vars will be imported from the environment in RAM. It makes more sense to keep the variable that is in the current environment but not in the imported environment if the H_NOCLEAR flag is set and remove only that variable if the H_NOCLEAR flag is not set. Let's clear the whole environment only if H_NOCLEAR and vars are not passed to himport_r. Let's remove variables that are in the current environment but not in the imported env only if the H_NOCLEAR flag is not passed.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

* env: import: hashtable: Prevent buffer overrun when importing environment ↵Lukasz Majewski2015-09-151-2/+3
| | | | | | | | | | | | | | | | | | | | | from file Lets consider following scenario: - One uses echo -n "key=value" to define environment variable in a file (single variable) - The file content is "key=value" without any terminating byte (e.g. 0x0a or 0x0d). - The file is loaded to u-boot non zero'ed RAM buffer (with load command). - Then "env import -t -r $loadaddr $filesize" is executed. - Due to lack of proper termination byte we have classical example of buffer overrun. This patch prevents from this by allocating one extra byte than size and explicitly null terminate it. There should be no change for normal env import operation after applying this patch.

* Add option -r to env import to allow import of text files with CRLF as line ↵Alexander Holler2014-07-221-1/+16
| | | | | | | | | | | | | | endings When this option is enabled, CRLF is treated like LF when importing environments from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored. Drawback of enabling this option is that (maybe exported) variables which have a trailing CR in their content will get imported without that CR. But this drawback is very unlikely and the big advantage of letting Windows user create a *working* uEnv.txt too is likely more welcome. Signed-off-by: Alexander Holler <holler@ahsoftware.de>

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).
