<div dir="ltr">Hello and greetings,<div><br></div><div>I am attempting to gain some insight into the decision making process that goes into the kernel configuration choices selected for a given variant kernel.  I have rummaged around the Ubuntu Kernel Wiki, applied search strings to the downloaded kernel-archive mailing list mbox, and bounced around on the Ubuntu Launchpad - all without finding either information on the general review process, or finding specifics on the particular detail I'm interested in.</div><div><br></div><div>What am I interested in exactly?  In the gcp kernel variants the CONFIG_UNICODE (UTF-8 normalization and casefolding support) option is disabled.  This configuration option arrived via (assuming I've trawled around correctly): <a href="https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-gcp/+git/eoan/commit/debian.gcp/config/config.common.ubuntu?id=2116ddb07ec8700610fbb17f751d76e0602a6109">https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-gcp/+git/eoan/commit/debian.gcp/config/config.common.ubuntu?id=2116ddb07ec8700610fbb17f751d76e0602a6109</a> , and was set to unset (off).</div><div><br></div><div>As to why, there are two guesses I might make:<br></div><div><br></div><div>One: As the gcp kernel variant already exists with a set of known configuration values, perhaps anything new and considered optional is left unset, until such time as an issue is made asking for it (example, <a href="https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1849493">https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1849493</a>) - perhaps I should submit an issue?  </div><div><br></div><div>Two: Perhaps this specific configuration was left unset per concerns a la <a href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-21300">https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-21300</a> - in which case submitting an issue would probably not be fruitful?  ( though I believe the post <a href="https://groups.google.com/g/linux.debian.kernel/c/cjjL57wyVYY/m/ld3tC39UBgAJ">https://groups.google.com/g/linux.debian.kernel/c/cjjL57wyVYY/m/ld3tC39UBgAJ</a> makes a nice case for why the CVE isn't precisely cause to leave this unavailable).</div><div><br></div><div>And of course, the rationale might be something I have no clue at - So I am asking if someone might point me in the right direction - either towards the background information I seek, or perhaps specifically suggesting that I open an issue.</div><div><br></div><div>My thanks, and I appreciate your time,</div><div>Lexi Haley</div><div><br></div><div>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:13pt;font-family:Verdana;color:rgb(0,0,0);font-weight:700;vertical-align:baseline;white-space:pre-wrap">Lexi Haley </span><span style="color:rgb(102,102,102);font-family:Verdana;font-size:13.3333px;white-space:pre-wrap">(she/her/hers)</span></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap">Computer Scientist, System Tools, Advanced Technology Division</span></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap">Medical Information Technology, Inc.</span></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap">Office: 781-774-5156 | Mobile: 508-713-2499</span></p><p style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><font face="Verdana"><span style="font-size:13.3333px;white-space:pre-wrap"><a href="mailto:lhaley@meditech.com" target="_blank">lhaley@meditech.com</a></span></font></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap">MEDITECH Circle, Westwood, MA 02090</span></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap">Main: 781-821-3000 | Fax: 781-821-2199</span></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;color:rgb(102,102,102);vertical-align:baseline;white-space:pre-wrap"><br></span></p><p dir="ltr" style="color:rgb(80,0,80);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:10pt;font-family:Verdana;c
