While most see coverage as a code quality metric, we see it primarily as a developer -productivity metric. When a developer makes a change to the codebase, presumably it's a *solution* to -some problem. Our unit-test suite is how we encode the set of *problems* the codebase solves. Running -the test suite should indicate that your change didn't *infringe* on anyone else's solutions. Adding a -test *protects* your solution from future changes. Say you don't understand why a line of code exists, -try deleting it and running the unit-tests. The nearest test failure should tell you what problem -was solved by that code. If no test fails, go ahead and submit a Pull Request that asks, "what -problem is solved by this code?" On the other hand, if a test does fail and you can think of a -better way to solve the same problem, a Pull Request with your solution would most certainly be -welcome! Likewise, if rewriting a test can better communicate what code it's protecting, please -send us that patch! - -# Disclaimer - -All claims, content, designs, algorithms, estimates, roadmaps, -specifications, and performance measurements described in this project -are done with the Solana Labs, Inc.

Accept the new report -In response a newly reported security problem, a member of the -`solana-labs/admins` group will accept the report to turn it into a draft -advisory. The `solana-labs/security-incident-response` group should be added to -the draft security advisory, and create a private fork of the repository (grey -button towards the bottom of the page) if necessary. - -If the advisory is the result of an audit finding, follow the same process as above but add the auditor's github user(s) and begin the title with "[Audit]". - -If the report is out of scope, a member of the `solana-labs/admins` group will -comment as such and then close the report. - -### 2. Triage -Within the draft security advisory, discuss and determine the severity of the issue. If necessary, members of the solana-labs/security-incident-response group may add other github users to the advisory to assist. -If it is determined that this not a critical network issue then the advisory should be closed and if more follow-up is required a normal Solana public github issue should be created. - -### 3. Prepare Fixes -For the affected branches, typically all three (edge, beta and stable), prepare a fix for the issue and push them to the corresponding branch in the private repository associated with the draft security advisory. -There is no CI available in the private repository so you must build from source and manually verify fixes. -Code review from the reporter is ideal, as well as from multiple members of the core development team. - -### 4. Notify Security Group Validators -Once an ETA is available for the fix, a member of the solana-labs/security-incident-response group should notify the validators so they can prepare for an update using the "Solana Red Alert" notification system. -The teams are all over the world and it's critical to provide actionable information at the right time. Don't be the person that wakes everybody up at 2am when a fix won't be available for hours. - -### 5. Ship the patch -Once the fix is accepted, a member of the solana-labs/security-incident-response group should prepare a single patch file for each affected branch. The commit title for the patch should only contain the advisory id, and not disclose any further details about the incident. -Copy the patches to https://release.solana.com/ under a subdirectory named after the advisory id (example: https://release.solana.com/GHSA-hx59-f5g4-jghh/v1.4.patch). Contact a member of the solana-labs/admins group if you require access to release.solana.com -Using the "Solana Red Alert" channel: - a) Notify validators that there's an issue and a patch will be provided in X minutes - b) If X minutes expires and there's no patch, notify of the delay and provide a new ETA - c) Provide links to patches of https://release.solana.com/ for each affected branch -Validators can be expected to build the patch from source against the latest release for the affected branch. -Since the software version will not change after the patch is applied, request that each validator notify in the existing channel once they've updated. Manually monitor the roll out until a sufficient amount of stake has updated - typically at least 33.3% or 66.6% depending on the issue. - -### 6. Public Disclosure and Release -Once the fix has been deployed to the security group validators, the patches from the security advisory may be merged into the main source repository. A new official release for each affected branch should be shipped and all validators requested to upgrade as quickly as possible. - -### 7. Security Advisory Bounty Accounting and Cleanup -If this issue is [eligible](#eligibility) for a bounty, prefix the title of the -security advisory with one of the following, depending on the severity: -- [Bounty Category: Critical: Loss of Funds] -- [Bounty Category: Critical: Consensus / Safety Violations] -- [Bounty Category: Critical: Liveness / Loss of Availability] -- [Bounty Category: Critical: DoS Attacks] -- [Bounty Category: Supply Chain Attacks] -- [Bounty Category: RPC] - -Confirm with the reporter that they agree with the severity assessment, and discuss as required to reach a conclusion. - -We currently do not use the Github workflow to publish security advisories. Once the issue and fix have been disclosed, and a bounty category is assessed if appropriate, the GitHub security advisory is no longer needed and can be closed. - - -## Security Bug Bounties -At its sole discretion, the Solana Foundation may offer a bounty for -[valid reports](#reporting) of critical Solana vulnerabilities. Please see below -for more details. The submitter is not required to provide a -mitigation to qualify. - -#### Loss of Funds: -$2,000,000 USD in locked SOL tokens (locked for 12 months) -* Theft of funds without users signature from any account -* Theft of funds without users interaction in system, token, stake, vote programs -* Theft of funds that requires users signature - creating a vote program that drains the delegated stakes. - -#### Consensus/Safety Violations: -$1,000,000 USD in locked SOL tokens (locked for 12 months) -* Consensus safety violation -* Tricking a validator to accept an optimistic confirmation or rooted slot without a double vote, etc. - -#### Liveness / Loss of Availability: -$400,000 USD in locked SOL tokens (locked for 12 months) -* Whereby consensus halts and requires human intervention -* Eclipse attacks, -* Remote attacks that partition the network, - -#### DoS Attacks: -$100,000 USD in locked SOL tokens (locked for 12 months) -* Remote resource exaustion via Non-RPC protocols - -#### Supply Chain Attacks: -$100,000 USD in locked SOL tokens (locked for 12 months) -* Non-social attacks against source code change management, automated testing, release build, release publication and release hosting infrastructure of the monorepo. - -#### RPC DoS/Crashes: -$5,000 USD in locked SOL tokens (locked for 12 months) -* RPC attacks - -### Out of Scope: -The following components are out of scope for the bounty program -* Metrics: `/metrics` in the monorepo as well as https://metrics.solana.com -* Any encrypted credentials, auth tokens, etc. checked into the repo -* Bugs in dependencies. Please take them upstream! -* Attacks that require social engineering -* Any undeveloped automated tooling (scanners, etc) results. (OK with developed PoC) -* Any asset whose source code does not exist in this repository (including, but not limited -to, any and all web properties not explicitly listed on this page) - -### Eligibility: -* Submissions _MUST_ include an exploit proof-of-concept to be considered eligible -* The participant submitting the bug report shall follow the process outlined within this document -* Valid exploits can be eligible even if they are not successfully executed on a public cluster -* Multiple submissions for the same class of exploit are still eligible for compensation, though may be compensated at a lower rate, however these will be assessed on a case-by-case basis -* Participants must complete KYC and sign the participation agreement here when the registrations are open https://solana.foundation/kyc. Security exploits will still be assessed and open for submission at all times. This needs only be done prior to distribution of tokens. - -### Duplicate Reports -Compensation for duplicative reports will be split among reporters with first to report taking priority using the following equation -``` -R: total reports -ri: report priority -bi: bounty share - -bi = 2 ^ (R - ri) / ((2^R) - 1) -``` -#### Bounty Split Examples -| total reports | priority | share | | total reports | priority | share | | total reports | priority | share | -| ------------- | -------- | -----: | - | ------------- | -------- | -----: | - | ------------- | -------- | -----: | -| 1 | 1 | 100% | | 2 | 1 | 66.67% | | 5 | 1 | 51.61% | -| | | | | 2 | 2 | 33.33% | | 5 | 2 | 25.81% | -| 4 | 1 | 53.33% | | | | | | 5 | 3 | 12.90% | -| 4 | 2 | 26.67% | | 3 | 1 | 57.14% | | 5 | 4 | 6.45% | -| 4 | 3 | 13.33% | | 3 | 2 | 28.57% | | 5 | 5 | 3.23% | -| 4 | 4 | 6.67% | | 3 | 3 | 14.29% | | | | | - -### Payment of Bug Bounties: -* Bounties are currently awarded on a rolling/weekly basis and paid out within 30 days upon receipt of an invoice. -* The SOL/USD conversion rate used for payments is the market price of SOL (denominated in USD) at the end of the day the invoice is submitted by the researcher. -* The reference for this price is the Closing Price given by Coingecko.com on that date given here: https://www.coingecko.com/en/coins/solana/historical_data/usd#panel -* Bug bounties that are paid out in SOL are paid to stake accounts with a lockup expiring 12 months from the date of delivery of SOL. diff --git a/accounts-db/src/account_overrides.rs b/accounts-db/src/account_overrides.rs index ee8e7ec9e2..d5d3286426 100644 --- a/accounts-db/src/account_overrides.rs +++ b/accounts-db/src/account_overrides.rs @@ -4,12 +4,16 @@ use { };
