Which command produced this string "DD-WRT v3.0-r52894 std (06/06/23)" in WEBUI's Status page?

Definitely not "uname -a", which only displayed kernel version.

The ssh pre-authentication banner also shows the versions info.

Code:

Was expecting something simpler....

In https://svn.dd-wrt.com/browser/src/router/httpd/visuals/lib.c#L94

Code:

websWrite(wp, "DD-WRT v3.0-r%s %s%s (" BUILD_DATE ") WW", SVN_REVISION, nvram_safe_get("dist_type"), DIST_OPT);

In https://svn.dd-wrt.com/browser/src/router/lsof/dialects/linux/Makefile.orig#L48

Code:

BUILD_DATE= $(shell date --utc --date=@$(SOURCE_DATE_EPOCH))

In https://svn.dd-wrt.com/browser/src/router/services/sysinit/sysinit.c#L2941

Code:

nvram_set("os_version", SVN_REVISION);

The WEBUI's string is "DD-WRT v3.0-r52894 std (06/06/23)"! I found that "nvram get os_date" was "May 15 2023", while "nvram get os_version" was "52894".

In https://svn.dd-wrt.com/browser/src/router/services/sysinit/defaults.c?rev=52830#L122

Code:

119 /*
120    * OS parameters
121    */
122    { "os_version", SVN_REVISION }, /* OS revision */
123    { "os_date", __DATE__ }, /* OS date */
124    { "wait_time", "5" },

"__DATE__" should have been "BUILD_DATE"? Because in https://svn.dd-wrt.com/browser/src/router/services/sysinit/init.c#L166 and in https://svn.dd-wrt.com/browser/src/router/services/sysinit/init.c#L211 , /tmp/loginprompt is created with "BUILD_DATE"!

Should we open a ticket on line 123 of defaults.c? Smile

And if "os_date" is not to be changed, should we introduce a nvram value "svn_date" or "build_date" which equals to BUILD_DATE?? A corresponding read-only value in /proc might also be useful.

Here is the current command-line that immitates the DD-WRT's version in the WEBUI's Status page:

Code:

echo "DD-WRT v3.0-r$(nvram get os_version) $(nvram get dist_type) ($(grep Release /tmp/loginprompt | cut -d : -f 2 | tr -d ' '))"

No.

Pointless.

Pointless.

I agree SVN_REVISION (and hence "os_version") indirectly indicates the build date of DD-WRT. But shouldn't both "os_date" and "os_version" refer to the version of DD-WRT, not the Linux kernel?

The only concern about changing NVRAM "os_date" is possibly this:

https://svn.dd-wrt.com/browser/src/router/services/services/cron.c#L146

Code:

if (nvram_matchi("hotss_enable", 1)) {
142
143    fp = fopen("/tmp/cron.d/hotss_checkalive", "w");
144
145    fprintf(fp,
146    "%d * * * * root /usr/bin/wget http://tech.hotspotsystem.com/up.php?mac=`nvram get wl0_hwaddr|sed s/:/-/g`\\&nasid=%s_%s\\&os_date=`nvram get os_date|sed s/\" \"/-/g`\\&install=2\\&uptime=`uptime|sed s/\" \"/\\%%20/g|sed s/:/\\%%3A/g|sed s/,/\\%%2C/g` -O /tmp/lastup.html\n",
147    (currtime->tm_min + 3) % 60, nvram_safe_get("hotss_operatorid"), nvram_safe_get("hotss_locationid"));
148
149    fclose(fp);
150    }

Also, loginprompt should have resided in /etc (instead of /tmp) as a read-only file. Anyway, it's not that important.
